Re: [R] Std Err on Concentration measures

Hi,
I'm using the ineq package to calculate some concentration measures
(Gini, Herfindal, ...) and I was wondering if there's around also a
function to calculate standard error on these measures. If not, is anybody
aware of where I can find a reference on this point?
Thanks.
There are several suggestions for estimating the variance of the Gini
coefficient:a literature search should reveal some suggestions.
If the sampling design is complex, you may be best off using a
resampling method, such as bootstrap.

[R] proportional matrix rows
Hi I have a two-column integer matrix like this: R jj [,1] [,2] [1,] -11 [2,] -22 [3,] -76 [4,] -87 [5,] -65 [6,] -98 [7,] -54 [8,]3 -3 [9,] -109 [10,] -43 I want a diagnostic that detects whether a row is a multiple of the first row or not. In this case, this would be rows 1,2, and 8. How to do this nicely? Sometimes the first row has a zero, so the method would have to work on [,1] [,2] [1,]01 [2,]11 [3,]08 [4,]0 -4 [5,]00 [6,]40 in which case rows 1,3,4,5 are multiples.

RE: [R] RODBC working in Rgui but not Rterm
On Mon, 7 Feb 2005, John Fox wrote: Dear Shlomo, Just last week I experienced a similar problem with RODBC and MySQL under Windows, though the problem extended to both Rterm *and* Rgui. After a fair amount of detective work, I discovered that the source of the difficulty was a newly downloaded MySQL ODBC Windows driver. When I instead installed a driver downloaded last December, everything worked fine. I've just confirmed that I can access MySQL from both Rterm and Rgui. I'm using R 2.0.1 under Windows XP. Since your symptoms are slightly different from mine, the ODBC driver may not be the source of the difficulty, but I thought that it might be worthwhile to mention it. There are two problems here 1) The latest MyODBC (3.51-10) has a problem that 3.51-07 did not have, as I found yesterday on both Linux and Windows (I am preparing an RODBC update). I've now read the sources, and it has a logic bug: it throws the error state IM008 Invalid window handle for connection completion argument whether or not any completion is needed. RODBC 1.1-3 will have a workaround for this. 2) There _is_ a documented difference between RGui and Rterm: see ?odbcConnect: Under the Windows GUI, specifying an incomplete 'connection', for example the default '', will bring up a dialog box to complete the information required. (This does not work from 'Rterm.exe' unless a driver is specified, a Windows restriction.) As a result of these two, MyODBC 3.51-10 ought to work under RGui and not under Rterm.

Do you mean that if fo is the formula then ls(environment(fo))
has many large components? I don't understand why that would
be a problem.
It can be a problem when you save a workspace. For example, the
.Rdata file produced by this session is tiny:
makef - function() {
+ y ~ x
+ }
fo - makef()
save.image()
while the file produced by this session is around 8 megabytes:
makef - function() {
+ z - rnorm(100)
+ y ~ x
+ }
fo - makef()
save.image()
You might assume that since z is local to the makef() call, and never
referenced by the formula, it wouldn't be saved: but you'd be wrong.
: It appears that we can't set the environment to NULL;
: should we set it to the Global environment e.g. using as.formula?
It works for me (R 2.1.0 Windows):
R fo - y~x
R environment(fo)
environment: R_GlobalEnv
R environment(fo) - NULL
R environment(fo)
NULL
It works for me too, so I'm not sure what problem Adrian was having.

[R] Rmatlab
Dear all, I came across recently to the Rmatlab package (http://www.omegahat.org/RMatlab/) that allows R and Matlab to talk to each other. I made several attempts to install it on my Mac but without any success as some headers seem to miss. I am just wondering if anyone has already tried and successfully used RMatlab. According to the website, this should run on unix machines and I was surprised that it couldn't be true for Mac as the OS X, Linux and Unix Matlab architectures are pretty much similar. Any inputs would be great! Thanks in advance for your help.

Re: [R] logit link + alternatives
I am not sure that fully answers Jeff's question. If the available link functions (even with the quasi family) are not sufficient for your needs, then you need to make your own constructor for a family object - which provides the necessary information to the glm engine - and use this as the family argument in your call to glm. Specifically, you need to make a copy of the binomial() function and replace the call to make.link().

Re: [R] subset data.frame with value != in all columns
Petr,
Thank you! Yes, rowSums appears to be even a little bit faster than
unique(which()), and it also maintains the original order. I do want
original order maintained, but I first apply a function to one of my
data.frames (that without any -s ... yes, these do represent nulls,
as someone asked earlier) and rbind these two dataframes back together,
so I need to sort (by rownames) after the rbind (there doesn't seem to
be a sortby option in rbind).
I apologize for not jumping on rowSums earlier, I hadn't caught on
that it was summing counts of occurrence of the search value, not
summing the search value itself.
Thanks again, this is very instructive and *very* helpful.
humbly,
Tim

Hi Tim
I can not say much about apply, but the code with unique(which())
gives you reordered rows in case of - selection
try
set.seed(1)
in.df - data.frame(
c1=rnorm(4),
c2=rnorm(4),
c3=rnorm(4),
c4=rnorm(4),
c5=rnorm(4))
in.df[in.df3] - (-)
system.time(e - in.df[unique(which(in.df == -, arr.ind =
TRUE)[,1]), ])
system.time(e1 - in.df[(rowSums(in.df == -)) != 0,])
all.equal(e,e1)
So if you mind you need to do reordering.
ooo-order(as.numeric(rownames(e)))
all.equal(e[ooo,],e1)
Cheers

How about this, presuming that your data frame is all numeric:
For rows containing -99:
x[unique(which(x == -99, arr.ind = TRUE)[, 1]), ]
c1 c2 c3 c4 c5
1 -99 1 1 10 1
2 -99 2 2 9 2
3 -99 3 3 8 3
44 4 -99 7 4
10 10 10 10 1 -99
For rows not containing -99:
x[-unique(which(x == -99, arr.ind = TRUE)[, 1]), ]
c1 c2 c3 c4 c5
5 5 5 5 6 5
6 6 6 6 5 6
7 7 7 7 4 7
8 8 8 8 3 8
9 9 9 9 2 9
What I have done here is to use which(), setting arr.ind = TRUE.
This
returns the row, column indices for the matches to the boolean
statement. The first column returned by which() in this case are the
row numbers matching the statement, so I take the first column only.
Since it is possible that more than one element in a row can match
the
boolean, I then use unique() to get the singular row values.
Thus, I can use the returned row indices above to subset the data
frame.
HTH,

Hi
I have a two-column integer matrix like this:
R jj
[,1] [,2]
[1,] -11
[2,] -22
[3,] -76
[4,] -87
[5,] -65
[6,] -98
[7,] -54
[8,]3 -3
[9,] -109
[10,] -43
I want a diagnostic that detects whether a row is a multiple of
the first row or not. In this case, this would be rows 1,2, and 8.
How to do this nicely? Sometimes the first row has a zero, so the
method would have to work on
[,1] [,2]
[1,]01
[2,]11
[3,]08
[4,]0 -4
[5,]00
[6,]40
in which case rows 1,3,4,5 are multiples. It'd be nice to have
a solution that works for any number of columns.

Re: [R] Programming/scripting with expressions - variables
Here is one way. It is the custom to return a value that will be assigned
to the variable, so I changed your 'macro' to a function that returns the
value and then assigns it to your variable:
test - function(name, value){
+ .result - NULL # initialize to NULL
+ .result[name] - value
+ .result[paste('other_', name, sep='')] - paste(other_, value,
sep='')
+ .result
+ }
Gregor - test('Gorjanc', '25')
Gregor# print out the vector
Gorjanc other_Gorjanc
25other_25

Hello to Rusers!
I am puzzled with R and I really do not know where to look
in for my problem. I am moving from SAS and I have difficulties
in translating SAS to R world. I hope I will get some hints
or pointers so I can study from there on.
I would like to do something like this. In SAS I can write
a macro as example bellow, which is afcourse a silly one but
shows what I don't know how to do in R.
%macro test(data, colname, colvalue);
data data;
...
colname=colvalue;
other_colname=other_colvalue;
run;
%mend;
And if I run it with this call:
%test(Gregor, Gorjanc, 25);
I get a table with name 'Gregor' and columns 'Gorjanc',
and 'other_Gorjanc' with values:
Gorjanc other_Gorjanc
25other_25
So can one show me the way to do the same thing in R?
Thanks!

[R] Help with multicomarisons after ANCOVA
Dear All, I' ve used ANCOVA (through lm(Y~factor*x)) to study the influence/differences between levels of factor upon the Y-x relationship. I found that both intercepts and slopes differ among levels of the factor. I understand from the results of summary(lm(Y~factor*x)) which of the intercepts/slopes per level differ from the reference level. I later used lm(Y~factor/(1+x)-1) to obtain explicit coefficients per level. My question is: Can I test for differences among all intercepts and /or slopes per levels using simtest (from package multicomp) as summary (simtest(Y~factor+x,type=tukey))?

Reading ?cor would have given you a solution: Quoting from ?cor If 'use' is 'all.obs', then the presence of missing observations will produce an error. If 'use' is 'complete.obs' then missing values are handled by casewise deletion. Finally, if 'use' has the value 'pairwise.complete.obs' then the correlation between each pair of variables is computed using all complete pairs of observations on those variables. This can result in covariance or correlation matrices which are not positive semidefinite. You have missing values in your data and with your usage of cor and argument use = all.obs precludes this. Choose another value for use, noting the advice in the help pages for cor. G At 08:32 AM 2/7/2005 -0800, Spencer Graves wrote: Have you considered cor?

Hello to Rusers!
I am puzzled with R and I really do not know where to look
in for my problem. I am moving from SAS and I have difficulties
in translating SAS to R world. I hope I will get some hints
or pointers so I can study from there on.
I would like to do something like this. In SAS I can write
a macro as example bellow, which is afcourse a silly one but
shows what I don't know how to do in R.
%macro test(data, colname, colvalue);
data data;
...
colname=colvalue;
other_colname=other_colvalue;
run;
%mend;
And if I run it with this call:
%test(Gregor, Gorjanc, 25);
I get a table with name 'Gregor' and columns 'Gorjanc',
and 'other_Gorjanc' with values:
Gorjanc other_Gorjanc
25other_25
So can one show me the way to do the same thing in R?
Thanks!

Lep pozdrav / With regards,
Gregor GORJANC
Greetings, Gregor, from a fan of Slovenia.
Here is a start. Multiple variables are often put together in data
frames. Your example did not include an input dataset name. I took
data to be an input data frame, and added two new variables. I assume
that colvalue and colname are character values. If colvalue has length
one it will be duplicated for each row of data.
test - function(data, colname, colvalue) {
data[[colname]] - colvalue
data[[paste('other',colname,sep='_')]] - paste('other',colvalue,sep='_')
data
}
Example usage:
data - data.frame(x=1:5, y=11:15)
data2 - test(data, 'a', 'b')
data - test(data, 'a', 'b') # over-write
test(data, 'a', 'b') # create data but don't store
with(test(data, ),{...})# reference variables in temporary
dataset
If we know what your ultimate goal is, there may be a much better
approach than the test function. In many cases, you do not need to
create new variables at all.

[R] install RMySQL

Re: [R] install RMySQL
Hi, Thank you for responding. One thing I forgot to mention (although I'm guessing you figured it out anyway) is that I'm running Mac OS X. I checked and I've got the file /usr/include/zlib.h installed on my machine. Is this enough for R or does it need a more robust installation of zlib? If this is enough, how do I let R know about the zlib.h file. If it's not, where should I get the correct zlib from? Thank you for any and all responses. -Xander On Mon, 2005-02-07 at 13:43, Roger D.

Hi Elijah, Thanks for the reply. I'm aware of almost all of those things you mentioned, and have played with some of them. I'm not looking to do distributed computing within R at this point. What I'm after, though, is not really addressed by any of them. I want a user to be able to start an interactive R session on a compute node that the system determines (dynamically) to be most available at the time. That's what `beorun' does, but I couldn't get it to run R interactively.

Oi Bernardo Maybe it would also be useful to show them some of the libraries available for medical research.

[R] MLE: Question
Hi R users! I have a likelihood ratio statistic that depends on a parameter delta and I am trying to get confidence intervals for this delta using the fact that the likelihood ratio statistic is approx. chi-squared distributed. For this I need to maximize the two likelihoods (for the ratio statistic) one of which depends on delta too and I am trying to use the function mle. But delta is neither a parameter I would like to estimate nor a fixed value that I know the value of (to give it to the mle function with fixed=list(delta=?)). Can I still use mle to find the likelihood of the data (just denoting delta as a constant)? Thank you.

[R] Nonparametric Split-Plot
Hello, I have several data sets involving repeated measures over time of annual grass survival in plots following application of several levels of herbicide treatments. Since the data set contains quite a number of zeros, it doesn't fit the assumptions for parametric analysis. I read in Shah, D.A. and L. V. Madden. 2004. Nonparametric analysis of ordinal data in designed factorial experiments. Am. Phytopathological Soc. 94:1 pp 33-43. that free macros exist for this analysis in SAS and R. I've looked through the R packages and searched the R mailing list; however, I can't seem to find what I'm looking for. Perhaps, I'm looking in the wrong place. I would appreciate it if someone would point me in the right direction.

Subject: Reading Dates in a csv File
Hi all. I'm reading in a flat, comma-delimited flat file using read.csv.
It works marvelously for the most part. I am using the colClasses
argument to, basically, create numeric, factor and character classes for
the columns I'm reading in. However, a couple of the fields in the file
are date fields. I'm fully aware that POSIXct can be used as a class,
however the field must obey, (I think), the standard/default POSIXct
format. Hence the following question: Does anyone have a method they can
share to read in a non-standard formatted date to convert to POSIXct? I
can read it in then convert it, but that's a two pass approach and not as
elegant as a single pass through read.csv. I've read, from the
documentation, that [o]therwise there needs to be an as method (from
package methods) for conversion from character to the specified formal
class but I do not know and have not figured out how to do that.
Any suggestion(s) would be greatly appreciated.
Thanks,
Charles

In the first case, the if expression is complete prior to
the else, hence the error. The second case completes since
the outer enclosing brace has not been processed. The third
case completes since the else is on the same line as brace
closing if expression and else expression not yet processed.
There may also be issues whether you're running interactively
or not. Recommend not using Whitesmith style brace formatting
with R or S-plus. IMO, the following formatting style works
best:
sety - function(x) {
if (x 0) {
y - 1
} else {
y - -1
}
}

My first thought was that all it looked a bit complicated for something that

I created a file called t.txt. I worked out the way I would have done it and
then I tested to see which was fastest. One little hiccup is that the two

made a typo somewhere. But then there may be something I have not come across.
