Re: [R] Efficient Way to gather data from various files
File operations are not vectorizable. About the only thing you can do for the iterating through files part might be to use lapply instead of a for loop, but that is mostly a style change. Once you have read the dbf files there will probably be vector functions you can use (quantile). Off the top of my head I don't know a function that tells you which value corresponds to a particular quantile, but you can probably sort the data with order(), find the value whose ecdf is just below your target with which.max, and look at the row number of that value. x - rnorm(11) names(x) - seq(x) xs - x[order(x)] Row90 - as.numeric(names (xs)[0.9=seq(xs)/length(xs))]) --- Jeff NewmillerThe . .

I know I can do it, but I always read online about how when using R one should always try to avoid loops and use vectors. I am wondering if there exists a more R friendly way to do this than to use for loops. I have a dataset that has a list of IDs. Let's call this dataset Master Each of these IDs has an associated DBF file. The DBF files each have the same title, and they are each located in a directory path that includes, as one of the folder names, the ID. These DBF files have 2 columns of interest. One is the run number the other is the statistic. I'm interested in the median and 90th percentile of the statistic as well as their corresponding run numbers. Ultimately, I want a table that consists of ID Run_50th Stat_50 Run_90 Stat_90 1AB 5102010 3 144376 1AC 399 6 9 etc. Where I currently have a dataset that has ID 1AB 1AC etc. And there are several DBF files that are in folders i.e. folder1/1AC/folder2/blah.dbf This dbf looks like run Stat 1 10 2 10 3 99 4 1000 5 1 6 99 7 1 8 10 9 10 1010 11 100 I know i could do this with a loop, but I can't see the efficient, R way. I was hoping that you experienced R programmers could give me some pointers on the most efficient way to achieve this result.

Re: [R] patch download?
That is silly. The primary difference is that certain bugfix patches have been applied. A side-effect of this first patched status is that unintentional bugs may have been introduced, so unless you have already encountered a bug that was patched there then you are likely better off sticking with the standard release. That said, I have had no qualms about using a patched version when I encountered a bug that got fixed. --- Jeff NewmillerThe . . Go Live... DCN:jdnew...@dcn.davis.ca.usBasics: ##.#. ##.#. Live Go...

Re: [R] Text to Speech In R
Please don't shout. Speech synthesis is associated in my mind with sound generation, which is rather platform-specific. R is a platform agnostic research tool. R can be interfaced with many kinds of external libraries, so many things are possible. However, they aren't necessarily simple, and hiding operating system differences can take a lot of work.

Re: [R] How to write out this regression equation in R?
But sprintf is itself vectorized. If you give it vectors, it returns vectors.
So you could obtain that apply-result more efficiently by passing a bunch of
column vectors of data. There happens to be a convenient object called a data
frame that holds a bunch of similar-length vectors.
DF - data.frame( m=c(1,2), b=c(-3,4) )
result - sprintf( y=(%d)*x+(%d), DF$m, DF$b)
cat(paste(result, collapse=\n))

Re: [R] Columns and rows
Data frames don't have unequal column or row lengths within a single object. Your terminology is obscuring your intent. Perhaps you should read the posting guide for guidance on posting here and then generate a reproducible example. Since you seem to be having difficulty with the how, at least provide sample input and desired output following the recommendations here: http://stackoverflow.com/questions/5963269/how-to-make-a-great-r-reproducible-example Are you aware of ?cbind ?rbind ?merge ? --- Jeff NewmillerThe . .

Re: [R] Columns and rows
Better, but you didn't do your reading. Seriously... learn to make it reproducible... you will get quicker help from more skilled R users. Also, post in text, not HTML. Note that data frames are not really the right data structure for doing the kinds of operations you are describing below, since you assume that rows and columns are essentially interchangeable. Lists of vectors might be, but only if you were reading from a data format like XML that reflected that structure. Matrices have a uniform 2d structure with a transpose operation defined, and can contain NA values. Also, vectors are not described as column or row vectors in R ... that is Matlab-speak. Vectors have no direction, just sequence. Matrices are folded vectors (vectors with row and column dimension attributes). The as.vector() function forgets the row and column attributes of a matrix (or other object). The matrix() function adds those attributes, effectively folding the vector up into 2d. Data frames are lists of vectors with the same length, where each vector can have a different type of data (e.g. string, numeric, logical, factor). They are printed, read from files and written to files with the vectors as columns (even though vectors themselves have no notion of being columns). Thus, working with one row at a time is much slower than working with one column at a time, and since each element of a row can be a different type of data it doesn't make sense to mash them up the way you want to. I suggest you print and use the str() function liberally on the objects and expressions below to understand how they work. #reproducible data DF - read.csv( text= Names,'Col x','Col y','Col z' rowName1,A,E,H rowName2,B,F,I rowName3,C,G,J rowName4,D,,K , header=TRUE, row.names=1, as.is=TRUE, quote=', na.strings= ) #solution mat - as.matrix( DF ) v1 - as.vector( na.omit( as.vector( t( mat ) ) ) ) v2 - as.vector( na.omit( as.vector( mat ) ) ) ans1a - matrix( v1, ncol=1 ) ans1b - matrix( v2, nrow=1 ) ans2a - matrix( v2, ncol=1 ) ans2b - matrix( v1, nrow=1 ) On Fri, 12 Oct 2012, Santana Sarma wrote: Hi, Trying to give an example here.

Re: [R] Filtering few column from one data frame based on another data frame
I suggest you go back to the Introduction to R document supplied with the software and read about indexing. In particular, pay attention to indexing into a matrix or data frame using data1[rowspec,columnspec] syntax. There are three kinds of row and column specification types, and any of the the three can be used to solve your problem. --- Jeff NewmillerThe . . Go Live...

Re: [R] Date Math
There are a few ways. The xts package has a lag function. So does zoo. Pay careful attention to the conventions used for specifying relative time in these various packages. You can also infill your missing data to create a regularly-spaced time series.

Asking questions and giving answers about R is what this mailing list is about. It is not really a theory list. If you understand the theory you can search among the libraries yourself. But when the first search I make brings up what to me looks like the answer to your question, then you either did not search before posting or you did not clarify what you were really looking for properly. --- Jeff NewmillerThe . .

Does elapsed = total actual time job taken ? That seems to be the case or a strange coincidence. Does user + system = CPU time from ps -aux | grep R ? That seems to be the case also or a weird coincidence. Finally, why can't the CPU get a higher percentage ? It's seems like it's always around 30% which would make sense since 5 is ~ 30% of 15 hours. Also, assuming my take above is correct, when talking about timing of algorithms, in this case, does one say the job took 5 hours or 15 hours ?

If you are wondering about Vector Autoregressive models, I don't claim any specific experience with them, but [1] says they are linear, and I do know that linear models respond in proportion to the magnitude of the input so you don't learn anything useful by changing the magnitude of the input.

FWIW, as described your problem is with Excel, and this is not an Excel support

Re: [R] SQL via RODBC
That would be very implementation-specific, and ODBC is generic in its own way. No, you must run one query at a time in general, and deal with the results using the procedural language. Keep in mind that you have to pick a back-end database to work with, and for creating the database you may have tools available that can directly process that sql file once.

Re: [R] asking about R Code
You seem to be quite lost. You should execute one statement at a time, and troubleshoot from there. I suspect that your attempts to get your file in the right place went wrong, or the file is the wrong type of file for that function (regardless of the name you gave it). As for giving you an explanation about read.pnm, I would rather not. There is documentation available on any library function using the ? command in R, e.g. ?read.pnm You should not have to replace files with other files in order to read them... you should be able to specify another name within the quotes. You may learn a bit about your current directory by using the getwd() function and the list.files() function. Once you have successfully read in the data, you can learn more about the object by following the useful hyperlinks in the documentation for read.pnm. I highly recommend reading the Introduction to R pdf that is supplied with your R software, and then reading the posting guide mentioned at the bottom of any email on this list. If your project is of an academic nature, the posting guide will remind you that this is not the place to ask homework questions... that is for you to obtain from your educational institution. --- Jeff NewmillerThe . .

Re: [R] using match-type function to return correctly ordered data from a dataframe
Have you actually read
?%in%
?
Although a valuable tool, not all answers are most effectively obtained by
Googling.
Also, your repeated assertions that the answers are not maintained in order are
poorly framed. They DO stay in order according to the zipcode database order.
That said, your desire for numeric indexes is only as far away as your help
file.

Re: [R] Having some Trouble Data Structures
Search on ragged array. My preferred approach is to use a data frame with one row per effector that repeats the per-ID information. If that occupies too much memory, you can setup another data frame with one row per ID and refer to that information as using lapply and subset the effectors data as needed. The plyr package is also useful for such processing. --- Jeff NewmillerThe . . Go Live... DCN:jdnew...@dcn.davis.ca.usBasics: ##.#. ##.#. Live Go... Live: OO#.. Dead: OO#..

What I need to have is a dataframe or table of some description - describing all the individuals of a pathogen population (so far I've implemented this as a matrix): ID No_of_Effectors Effectors (Sequences) [1,] 0001 3 ## 3 Random Numbers ## There will be many such rows for many individuals. They have something called effectors, the number of which is randomly generated, so say you get 3 in the No_of_Effectors column. Then I make R generate 3 numbers from between 1 and 10,000, this gives me three numerical representations of genes. These numbers will be compared to a similar data structure of the host individuals who have their immune genes with similar numbers. My problem is that obviously I can't stick 3 numbers in one cell of the matrix (I've tried) : Pathogen_Individuals[1,3] - c(2,3,4) Error in Pathogen_Individuals[1, 3] - c(345, 567, 678) : number of items to replace is not a multiple of replacement length In future I'm also going to have more variables such as whether a gene is expressed. Such information may require a matrix in itself - something like: Effector ID Sequence Expressed? [1,] 0001 345,567,678 1 (or 0). Is there a way then I can put more than one value in the cell like a list of values, or a way to put objects in a cell of a data frame, matrix or table etc. Almost an inception deal - data structures nested in a data structure? If I search for things like insert list into matrix I get results like how to turn one into another, which is not what I think I need to be doing. I have been considering having several data structures not nested in each other, something like for every individual create a new matrix object with the name Effectors_[Individual_ID] and some how get my simulation loops operating on those objects but I find it hard to see how to tell R all of those matrices are to be included in an operation, as you can all lines of a data frame for example with for loops. This is strange for me because this model was written in a macro-code for another program which handles data in a different format and layout to R. My problem is I think, each individual in the model has many variables - in this case representations of genes. So I'm having trouble getting my head about this.

Re: [R] mergeing a large number of large .csvs
I would first confirm that you need the data in wide format... many algorithms
are more efficient in long format anyway, and rbind is way more efficient than
merge.
If you feel this is not negotiable, you may want to consider sqldf. Yes, you
need to learn a bit of SQL, but it is very well integrated into R.

Re: [R] mergeing a large number of large .csvs
On the absence of any data examples from you per the posting guidelines, I will
refer you to the help files for the melt function in the reshape2 package.
Note that there can be various mixtures of wide versus long... such as a wide
file with one date column and columns representing all stock prices and all
trade volumes. The longest format would be what melt gives (date, column name,
and value) but an in-between format would have one distinct column each for
dollar values and volume values with a column indicating ticker label and of
course another for date.
If your csv files can be grouped according to those with similar column
types, then as you read them in you can use cbind( csvlabel=somelabel,
csvdf) to distinguish it and then rbind those data frames together to create an
intermediate-width data frame. When dealing with large amounts of data you will
want to minimize the amount of reshaping you do, but it would require knowledge
of your data and algorithms to say any more.

Re: [R] date and time coding question
I stand by my previous statement: you should avoid thinking of difftime objects as having units.

Re: [R] as.vector with mode=list and POSIXct
I don't know what you plan to do with this list, but lists are quite a bit less
efficient than fixed-mode vectors, so you are likely losing a lot of
computational speed by using this list. I don't hesitate to use simple data
frames (lists of vectors), but processing lists is on par with for loops, not
vectorized computation. It may still support a simpler model of computation,
but that is an analyst comprehension benefit rather than a computational
efficiency benefit.

The POSIXct values are coerced to numeric, which is unexpected.
The documentation for as.vector says: The default method handles 24
input types and 12 values of type: the details of most coercions are
undocumented and subject to change. It would appear that treatment for
POSIXct is either missing or needs adjustment.
Unlist (for the reverse) is documented to converting to base types, so
I can't complain. Just wanted to share that I ended up giving up on
vectorization and writing the two following functions:
unlistPOSIXct - function(x) {
retval = rep(Sys.time(), length(x))
for (i in 1:length(x)) retval[i] = x[[i]]
return(retval)
}
listPOSIXct - function(x) {
retval = list()
for (i in 1:length(x)) retval[[i]] = x[i]
return(retval)
}
Is there a better way to do this (other than using *apply instead of
for above) that better leverages vectorization? Am I missing something
here?
Thanks!

Re: [R] as.vector with mode=list and POSIXct
I recommend that you not plan on waiting for the hash package to be redesigned to meet your expectations. Also, your response to discovering this feature of the hash package seems illogical. From a computer science perspective, the hash mechanism is an implementation trick that is intended to improve lookup speed. It does not actually represent a fundamental data structure like a vector or a set does. You can always put your keys in a vector and search through them (e.g. vector indexing by string) to get an equivalent data retrieval. If the hash package is not improving the speed of your data access, adding an extra layer of data structure is hardly an appropriate solution. Why are you not using normal vectors or data frames and accessing with string or logical indexing? If you are avoiding vectors because they seem slow in loops, perhaps you just need to preallocate the vectors you will store your results in before your loop to regain acceptable speed. Or, perhaps the duplicated() or merge() functions could save you from this mess of incremental data processing. --- Jeff NewmillerThe . . Go Live... DCN:jdnew...@dcn.davis.ca.usBasics: ##.#. ##.#.

Re: [R] as.vector with mode=list and POSIXct
My perception of illogic was in your addition of more data structure complexity when faced with this difficulty. R has best performance when calculations are pushed into simple typed vectors where precompiled code can handle the majority of the work. These are simpler structures, not more complex structures. It seems like you are fighting the natural paradigm for working in R and holding fast to your ideas about how things should be rather than dealing with how they are by introducing lists rather than working with vectors or data frames. --- Jeff NewmillerThe . .

Alexandre Sieira alexandre.sie...@gmail.com wrote: Hi, Jeff. Thanks for your thoughtful suggestions. I do not plan to wait for the hash package to be redesigned to meet my expectations. As a matter of fact, I have: a) Submitted a report of unexpected behavior in hash::values, which the package maintainer quickly replied to and said would examine. b) Designed (with the help of this list) and implemented a workaround in the form of wrapping the POSIXct objects in lists, which has my program working correctly for now. If the hash package is updated and the workaround is no longer necessary, then I'll reverse this change. Otherwise, I'll look more deeply into my alternatives which might involve maintaining this workaround permanently, or analyzing alternative architectures. The hash package is a beautiful piece of code that is working perfectly for me in many situations. Even with the list wrapping around the POSIXct objects, it is meeting my performance requirements much better than the alternatives I tested. So I'd rather not completely re-engineer working complex code without a very good reason. However, I would like to respectfully disagree with you that my reaction to hash::values behavior was illogical. I don't want to start a flame war or anything, so let's try to keep the discussion civil. :) See, a hash table (or a queue, or a stack, or an R vector) is a data structure that works as a container. You insert objects and you get them back according to the specificities of each data structure (stacks will have a FILO ordering, queues will have FIFO ordering, hashes will maintain key/value pairs, and so). It is completely unreasonable to insert an object of class X into a container, and then get it back altered in a way that is not part of the 'contract' behind the data structure. If I assign X to key K on a hash, however I choose to ask the hash for the value associated with key K back, I should get exactly X as a response. I believe most computer scientists would agree that to be self-evident. And that is to be expected by reading hash::values documentation: Extract values from a hash object. This is a pseudo- accessor method that returns hash values (without keys) as a vector if possible, a list otherwise. Moreover, it has this to say about non-primitive types: If the values are of different types or of a complex class than a named list is returned. It never says it will unclass objects, or coerce them into primitive types. Hence the 'contract' implies I will get back what I inserted, unaltered, either in a vector or a list. And that is provably not what is happening. I would have been ok with a vector of POSIXct or a named list containing the POSIXct values, but instead I am getting a numeric vector. I understand R is based on S, and that OOP concepts were introduced later into its history. However, one of the key concepts in OOP is encapsulation - as an outside entity you do not get to see the internal implementation of a class, you interact with it exclusively through its published interface (method, public member variables, etc). I cannot find any justification as for why an object losing its class unintentionally is ever acceptable, as it violates the concept of encapsulation. That is essentially what's happening if I look up several keys using values(). So this violates the encapsulation of the POSIXct class, as I am exposed to its internal numeric value. Moreover, it breaks the method-dispatch of R functions that know to treat POSIXct values differently. All of a sudden, the POSIXct objects I inserted are being treated, for example, by format as numeric instead of being dispatched to format.Date as expected. So I don't think my reaction to this issue was illogical at all. Hope you'll agree now that I've explained myself a little better. :) -- Alexandre

Re: [R] Could graph objects be stored in a two-dimensional list?
You could use lists of lists, and index them with vectors.
a - list()
a[[1]] - list()
a[[2]] - list()
a[[c(1,1)]] - g11
a[[c(1,2)]] - g12
a[[c(2,1)]] - g21
a[[c(2,2)]] - g22
print(a[[c(2,1)]])
but this seems like an inefficient use of memory because your indexed data is
stored more compactly than the graph object is. I would index the data and
generate the graph object on the fly when I wanted to see it.

Hi,
I have a few graph objects created by some graphic package (say,
ggplot2,
which I use frequently). Because of the existent relation between the
graphs, I'd like to index them in two dimensions as p[1,1], p[1,2],
p[2,1],
p[2,2] for convenience.
To my knowledge, the only data type capable of storing graph objects
(and
any R object) is list, but unfortunately it is available in only one
dimension. Could the graphs be stored in any two-dimensional data type?
One remedy that comes to my mind is to build a function f so that
f(1,1)=1
f(1,2)=2
f(2,1)=3
f(2,2)=4
With functions f and f^{-1} (inverse function of f) , the
two-dimensional
indices could be mapped to and from a set of one-dimensional indices,
and
the functions are exactly the way R numbers elements in a matrix. Does
R
have this built-in function for a m by n matrix or more generally,
m*n*p
array? (I know this function is easy to write, but just want to make
sure
whether it exists already)
Thanks,
Miao

I am working with spatial data in ggmap, generally with great success.
I have a huge data set with the coordinates in NAD 83 UTM Zone 11

to aggregate the data :

color = hc, ,alpha=a,stat = identity) +
scale_fill_gradientn(Mean,colours=rev(rainbow(4)),trans='sqrt')
...and so on for other stats
I can also run statistical analyses on hx_dat.
By creating hexbins based on lat/long it seems there will be distortion
due to the differences in length of a degree at different locations on
the earth's surface. What is the most efficient way to eliminate this
distortion? Should I run hexbin in NAD83 and convert the x/y
coordinates to Lat Long? Can I get ggmap to convert the baselayer to
NAD84 and just do everything in NAD(my preferred option)?
I have tried converting Lat Long to NAD84 and back but the coordinates
are coming up in the eastern Pacific and not in California, so I am
missing something and I am not sure that is the best way to solve the
problem anyway. Thanks in advance, any help is greatly appreciated

Re: [R] curiosity: next-gen x86 processors and FP32?
I am no HPC expert, but I have been computing for awhile. There are already many CPU-specific optimizations built into most compilers used to compile the R source code. Anyone sincerely interested in getting work done today should get on with their work and hope that most of the power of new processors gets delivered the same way. The reason single precision is so uncommon in many computing environments is that numerical errors propagate much faster with single precision. I don't expect the typical R user to want to perform detailed uncertainty analysis every time they set up a computation to decide whether it can be computed with sufficient accuracy using SP. Most speed problems I have encountered have been related to memory (swapping, fragmentation) and algorithm inefficiency, not CPU speed. --- Jeff NewmillerThe . . Go Live...

I like R to be fast and effortless. I don't want to have to rewrite my code greatly to take advantage of my CPU. the CUDA forth-and-back on the memory which requires code rewrites makes CUDA not too useful for me. in fact, I don't even like setting up computer clusters.

I presume that any quantum leaps would have to come from R using a different numerical vector engine. (I tried different compiler optimizations when compiling R (such as AVX) on the 1-year old i7-27*, but it did not really make a difference in basic R benchmarks, such as simple OLS calculations. I thought AVX would provide a faster vector engine, but something didn't really compute here. pun intended.) I would guess that haswell will be a nice small evolutionary step forward. 5-20%, perhaps. but nothing like a factor 2. [tomshardware details how intel FP32 math is 4 times as fast as double math on the i7 architecture. for most of my applications, a 4 times speedup at a sacrifice in precision would be worth it. R seems to use only doubles---even as.single is not even converting to single, much less inducing calculations to be single-precision. so I guess this is a no-go. correct?? ] kaveri's hUMA on the other hand could be a quantum leap. kaveri could have the GPU transparently offer common standard built-in vector operations that we use in R, i.e., improve the speed of many programs without the need for a rewrite, by a factor of 5? hard to believe, but it would seem that AMD actually beat Intel for R users. a big turnaround, given their recent deemphasis of FP on the CPU. (interestingly, the amd-built Xbox One and PS4 processors were also reported to have hUMA.) worth waiting for kaveri? anything I can do to drastically speed up R on intel i7 by going to FP32? regards, /iaw Ivo Welch (ivo.we...@gmail.com) __ R-help@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide http://www.R-project.org/posting-guide.html and provide commented, minimal, self-contained, reproducible code. __ R-help@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide http://www.R-project.org/posting-guide.html and provide commented, minimal, self-contained, reproducible code.

Re: [R] adding class attributes to strings: works in a loop, but not directly
a) You cannot assign attributes to literal values such as BICY. You must
assign them to variables, as in
x - BICY
class(x) - AONmode
b) You cannot give the separate elements of a vector their own separate
attributes unless the vector is of mode list. Ordinarily, attributes apply to
the whole vector. (When the vector is of mode list then each element may be a
vector on its own with its own attributes.)
y - c(FOOT,BICY)
class(y) - AONmode
z - vector( list, 2 )
z[[1]] - FOOT
class( z[[1]] ) - AONmode
z[[2]] - BICY
class( z[[2]] ) - AONmode

Dear all
I try to assign class attributes to strings. Depending on the approach
I use, it works (including method dispatch) or fails.
Let me clarify with an example.
Let:
AONtptmodelist - c(FOOT,BICY)
When I assign class attributes directly to these strings, it fails:
class(BICY) - AONmode
Error in class(BICY) - AONmode :
target of assignment expands to non-language object
However, when I assign the attributes in a loop, it does work:
for(tptmode in AONtptmodelist) {
+ class(tptmode) - AONmode
+ cat(The value of is.object(tptmode) for , tptmode , is: ,
is.object(tptmode) , .\n)
+ cat(The class of , tptmode , is: , class(tptmode) , .\n)
+ }
The value of is.object(tptmode) for FOOT is: TRUE .
The class of FOOT is: AONmode .
The value of is.object(tptmode) for BICY is: TRUE .
The class of BICY is: AONmode .
Moreover, within this loop, method dispatch works correctly.
However, when I start a new loop over the same vector, I get:
for(tptmode in AONtptmodelist) {
+ cat(The value of is.object(tptmode) for , tptmode , is: ,
is.object(tptmode) , .\n)
+ cat(The class of , tptmode , is: , class(tptmode) , .\n)
+ }
The value of is.object(tptmode) for FOOT is: FALSE .
The class of FOOT is: character .
The value of is.object(tptmode) for BICY is: FALSE .
The class of BICY is: character .
I find this troublesome for two reasons. First, I do not understand the
difference between the two approaches. Why can I assign a class
attribute to a string when it is called in a loop, but not directly?
And why is the class attribution not permanent? Second, the problem was
concealed until now precisely because I assigned the attributes in a
link. However, I would like to centralise my class definition in one
single place in my code, thus outside the loop where the methods are
called.

Re: [R] write table in ascii
I would bet the problem is end-of-line convention. This is a very old problem of text file conversion that has many solutions, none of which should be addressed by R. Rather, you should use any of the many standard file transfer mechanisms that understand EOL issues in text files, rather than transferring the data as if it were binary data. Email is one such mechanism, FTP is another. Many text editors can also fix this for you. It is possible to fix it in R, but that is a very bad approach.

Re: [R] Loop FOR with histogram() from lattice
If you have read the Posting Guide, you will know that you should have read ALL
the FAQs before posting your question.
http://cran.r-project.org/doc/FAQ/R-FAQ.html
That said, this particular FAQ applies to any library that depends on grid
graphics, including lattice and ggplot2.

Hi Jim,
Thank you a lot. Is it a FAQ concerning lattice or FOR loop in general?

This is an FAQ. you have to explicitly 'print' the histogram:
print(histogram(~ Mpool[[2]]$LngtClas | Mpool[[2]]$SpCode, type =
count, col = lightgrey, xlab= LngtClas, main = paste(Length
distribution per species for Mpool, 2, sep = _)))

Hi all,
I'm encountering a problem I do not understand on my data:

This part works perfectly and I obtain the graph reprensenting
Mpool2 length class count per species.
Now when I want to automatize this with a for loop nothing is
plotted.
for (i in c(2)){
windows()
histogram(~ Mpool[[i]]$LngtClas | Mpool[[i]]$SpCode, type = count,
col = lightgrey, xlab= LngtClas, main = paste(Length distribution
per species for Mpool, i, sep = _))
print (i)
}
### Running this loop I obtained windows filled grey (no plot drawn
at all) but the print (i) print a 2 as expected. I really dont
understand what's wrong with the loop. There is no error message and no
notification in R. You can find enclosed my data in txt file.
Thank you very much for any help,

Re: [R] Fortunes nomination (was: colour coded dotchart)
Oh, Lord, give me strength, for I am about to read an R Help file! Give me insight, for I must parse the words of statisticians forced by R CMD check to follow the way of the Literate Programmer! And please, Oh Lord, give me the wisdom to recall these tribulations when I set foot upon that road, that I may mark the path I blaze clearly for the novitiate to follow yet my words not become as obscure as those I read! Commentary: There is both truth and fiction in Rolf's advice, and for the truth I applaud the nomination, but for the fiction I fear the picture it paints in the unsuspecting mind. On the one hand, it seems odd to ask that the R user believe that meaning is there because this is software, not the Bible. On the other hand, some people seem to think they should not have to study to use this tool properly, so perhaps some faith will help them dig a little harder. Writing documentation is hard, and R CMD check at least makes package developers write SOMETHING down. That doesn't mean that it verifies that it is complete or clearly written. You can drag the horse to water but you cannot make them drink. Fortunately, the author of the code often does write just what you need to use it... even if it is a bit terse. There is also a bit of transformation that happens as one learns how R code works, that makes the obscure documentation more intuitive. What the beginner does not seem to realize is that documentation that they would think is perfect would likely have to be customized to fit their specific set of educational holes, but would bore others who knew all that stuff. The solution is for certain conventions and shorthand to be used, and to let the user search as deep as they need to get their answer. Also, it is common for teenagers to say they will never be like their parents, yet later find themselves doing just that. It is worth reminding new users that the maintainer() function is the key to helping improve R documentation, since what beginners think of as R is not a monolithic product but rather is the product of many individuals. Having the package maintainer be the gateway for such changes is a bit random, since different maintainers have different time and skills for the job, but communicating with the right person (rather than expecting them to read every message on R- help) is in general the best practice for fixing problems in packages. (Faulty documentation is indeed a problem, but a constructive suggestion for fixing it is far more likely to bring about change than either throwing of stones or abasing oneself before the guru.) --- Jeff NewmillerThe . .

Re: [R] Fwd: Problem with ODBC connection
Given the resounding silence, I would venture to guess that no-one here is interested in troubleshooting ODBC connections to Excel.

Re: [R] Big, complex, well-structured .R file for demonstration?
Just because you have an editor that can let you see the organization within the file does not mean the code itself is well-structured. If you do put a lot of code in one file, you will be more likely in your next project that builds on this one to load code you do not need (bloat), and that is a very practical defect in the structure of the current project. Regardless of any arguments you can think of to the contrary, that is why single large files with otherwise well-structured code are uncommon. --- Jeff NewmillerThe . . Go Live...

Re: [R] R session freezes when I try to save a new script
You will probably need to read the Posting Guide and follow its recommendations to get a constructive response. Things like posting in text instead of HTML and providing the output of sessionInfo go a long way toward speeding up the troubleshooting process. You can also begin the process of identifying what your in-memory objects look like by stopping your script just before you run the function or click on a menu that hangs, and providing to us the output of the ls() function in your next email. You may have redefined an object with an important name. Alternatively, you may have a windows permissions issue (which would be outside the scope of this mailing list. Ideally you would generate a self- contained reproducible example, but if that is not possible then you will have to live with guesses as responses.

Re: [R] BINARY traits GENETIC CORRELATION
Re-posting, particularly without referencing your earlier post, is bad mailing-list etiquette. Posting in HTML is particularly frowned upon here also. Nor is this a statistical methods support forum... it is about R. I for one am finding your question very jargonish and obscure. If your question is straightforward in the genetics domain then there might be more responsiveness in the Bioconductor mailing list. Otherwise, you may need to frame your question more directly in terms of the R language, with an example starting data set and expected results [1].

The R package is a great tool that has advanced to a level that now we can estimate whole genome-enabled breeding values in genomic selection research. So, with the aim of moving out of those packages (listed above) which are either expensive or have little support, I would like to know if we can estimate Rg between two binary traits (disease status: alive vs. dead) with the R package. My data: we have 100 full-sib (FS) families, and two random samples (each with n= 200 FS fish) from each FS family were evaluated for resistance response to two different bacterial diseases, separately. It implies that both traits are not recorded in the same individual; each trait is recorded in different groups of full-sibs (random sampled from a FS family). So using this family relationship (full-sibs), I would like to estimate the Rg between these two disease resistance traits; of course I would like to estimate Rg with the R package. I will appreciate having directions on which R package to use if any, or combination of R functions needed to use to calculate the Rg (between two binary traits; disease survival traits).

Possibly I need to completely clean out the installation and start again? but I'm not sure precisely where the R support files are stored on Macs. Can anyone give me a pointer and/or suggest an alternative fix? R 2.11.1 is a rather archaic version. The current version is 3.0.1. You seems to have skipped major versions 2.12, 2.13,, 2.14 2.15.

Re: [R] Data Package Query
data is a base function (so you should not have to load any packages to use it), and it is not capitalized. Depending on the particular data set you want the data function to load, you may need to load the package that contains that data set. A common error by beginners (which may or may not be your problem in this case) is to create a variable called data. Unfortunately this hides the function named data and from that time forward that R session doesn't work when you type example code that uses the data function. If this is your problem, the best solution is to restart R and do your analysis from the beginning using a different variable name than data.

Re: [R] [SPAM?] Re: Data Package Query
Please reply to all so the thread stays on the mailing list for all to see (and correct if wrong information is given). Regarding your code below, either you are missing a library statement to load a package that contains this trial data, or you are intending to read in your own data set but are not yet aware of how that is done. I could find no package containing a data set named trial (but I might have missed one). If you have some data of your own, then the data function is almost certainly not the right tool for the job. A PDF document called R Data Import/Export is supplied with R that can get you started. There are also various intro books available. --- Jeff NewmillerThe . . Go Live...

Re: [R] Data Package Query
You need to learn to execute one statement at a time in order to debug this yourself. Copy and paste is your friend. Hint: I already told you that the data function is inappropriate if the data does not come from a package. You should be learning to use the str(), head(), and ls() functions to explore your R in-memory environment, and use the built-in help system with the question mark (?str) or the help.search() and RSiteSearch() functions. --- Jeff NewmillerThe . .

I believe it *used* to be true, sometime wa back, but hasn't been true for years. The R language is much cleverer now. If there is a function melvin() somewhere on the search path and also a data object melvin (earlier on the search path) then doing melvin(whatever) will correctly call the function melvin() with no complaints. The R language can tell by the parentheses that you mean the *function* melvin and not the data object melvin.

All that being said it is ***BAD PRACTICE***, just in terms of comprehensibility and avoiding confusion, to give a data set set the same name as a function (either built in, or one of your own). fortune(dog) is relevant. cheers, Rolf Turner __ R-help@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide http://www.R-project.org/posting-guide.html and provide commented, minimal, self-contained, reproducible code.
Re: [R] Bhattacharyya in R
There is a built-in guide to syntax called the help system. If you have read it you should be able to be mitre specific with your questions. I had never heard of this function. Your example code is not reproducible, nor does it indicate what result you got from running it. I used RSiteSearch(bhattacharya) and there appears to be a function bhattacharyya.matrix in the fpc package. The syntax indicated in the help for that function mentions wanting input matrices, not vectors. It also mentions another function bhattacharyya.dist which does accept vectors, but it does not accept the misclassification.bound argument. You should read the help file and ask more specific questions and provide reproducible examples per the Posting Guide recommendations. --- Jeff NewmillerThe . . Go Live...

Re: [R] Lee carter model
The Posting Guide warns you to not post in HTML format (it messes up R code examples). It also warns you to supply reproducible examples (we should be able to paste your code into a fresh R session and see essentially what you see). The warning message means you have given the function a factor where it expected a numeric value (max does not work on factors). I suggest that you learn how to use the str() function on your data so you know that you have imported it successfully before you give it to analysis functions. You may need to review the Introduction to R and R Data Import/Export PDF files that come with R if you don't know what a factor is or how to import numeric data. --- Jeff NewmillerThe . . Go Live...
