Subject: Re: [R] Extract values from vector and repeat by group
Hi,
?merge() sometimes change the order.
For example:
df1 - df[-12,]
df2 - df1
merge(df1, df1[df1$time == 4, c(group, var)], by.x = group, by.y =
group, suffixes = c(, GroupSK0))
In that case,
df1$ord1 - with(df1,order(group,time))
res - merge(df1, df1[df1$time == 4, c(group, var)], by.x = group, by.y =
group, suffixes = c(, GroupSK0))
res[order(res$ord1),-4]
#or just
library(plyr)
join(df2,df2[df2$time==4,c(group,var)],by=group,type=inner)
#or you may use:
indx - with(df1,ave(time==4,group,FUN=any))
ddply(df1[indx,],.(group),mutate,new=var[time==4])
A.K.

Hi all,
I hope you can help.
I have a data frame 'df':
group=c(rep(1,8),rep(2,10),rep(3,11))
var=rnorm(29)
time=c(seq(1,8),seq(1,10),seq(1,11))
df=data.frame(group,var,time)
I would like to extract the value from 'var' for each 'group' at 'time'=4 and
repeat these extracted values in a new vector ('new') n times where n is the
number of rows for each group. I did this by hand as below, but there must be
a quicker way:
subset=subset(df,df$time==4)
subset
groupvar time
4 1 0.25312704
12 2 -0.36001284
22 3 0.41947304
df$new=c(rep(0.2531270,8),rep(-0.3600128,10),rep(0.4194730,11))
Any questions please ask,
A very similar question was recently asked on Stackoverflow:
http://stackoverflow.com/questions/19971763/r-programming-normalizing-a-column-of-data-by-another-entry-in-2-other-columns
From the answer given there you could try this
set.seed(11) # to make it reproducible
group=c(rep(1,8),rep(2,10),rep(3,11))
var=rnorm(29)
time=c(seq(1,8),seq(1,10),seq(1,11))
df=data.frame(group,var,time)
#df
#df[df$time==4, c(group, var)]
# merge into original data.frame
df - merge(df, df[df$time == 4, c(group, var)], by.x = group, by.y =
group, suffixes = c(, GroupSK0))
df

[R] Anova split by factors
Hello R-users, I have a problem with Anova in R and I don't know how to solve that. I want to compute Anova for each experiment (exp). I try this code: test-lapply(split(eg,eg$Exp),function(x) aov(masa.uscat.tr ~ Clona,data = x)) or test-by(eg,eg$Exp, function(x) aov(masa.uscat.tr~Clona,data=x)) I want to compute Anova summary for each experiment (exp) and I want to compute Tuckey test for each Anova. Thank you very much! My data is like this: Exp Plot Clona Prov masa uscat tr masa usc.

Dear Catalin,
Have a look at the plyr package.

[R] Sending a matrix in an email

Below is the command to output my coefficients: write.table(zbetas, file = z_coeffs.csv, sep=\t, append = TRUE) I do this run multiple times. It appends the latter results to the end of my .csv file. Is there a way to say just before the write.table something to the effect of: title(First Run, append = TRUE)? Or perhaps there is a sub-command in the write.table to accomplish this. So when I interactively run my code it could be something like: First run Coeff1 0.34 Coeff2 0.96 Second run Coeff1 0.47 Coeff2 0.95 Thank you very much in advance.

Re: [R] issues with calling predict.coxph.penal (survival) inside a function
Hello,
and thanks for the answer.
1) I found a work-around - in the end it is easier than thought before.
The only thing you have to do is to have the same variable name with the
new values.
So if predict(coxph.penal.fit, newdata[subset,]) does not work inside a
function, the following works:
pred_function - function(coxph_model, newdata){
#things to do before
newdata=newdata[the_subset_i_want,]
predict(coxph_model, newdata)
}
I attach a working example.
I am not sure, maybe this is even what is written in the help to
NextMethod ;)
NextMethod works by creating a special call frame for the next method.
If no new arguments are supplied, the arguments will be the same in
number, order and name as those to the current method but their values
will be promises to evaluate their name in the current method and
environment. Any named arguments matched to ... are handled specially:
they either replace existing arguments of the same name or are appended to
the argument list. They are passed on as the promise that was supplied as
an argument to the current environment. (S does this differently!) *If
they have been evaluated in the current (or a previous environment) they
remain evaluated.* (This is a complex area, and subject to change: see the
draft R Language Definition.) (Help to NextMethod )
2) Terry, I am not sure about the work-around you provided in your mail. I
want to do subsetting on newdata, not on the model.
Additionally, when trying the example you provided, I received different
results. Example is attached.
Thanks and all the best

Betreff: Re: issues with calling predict.coxph.penal (survival) inside a
function
Thanks for the reproducable example. I can confirm that it fails on my
machine using survival 2-37.5, the next soon-to-be-released version,
The issue is with NextMethod, and my assumption that the called routine
inherited everything from the parent, including the environment chain. A
simple test this AM showed me that the assumption is false. It might have
been true for Splus. Working this out may take some time -- every other
one of my wrestling matches with predict inside a function has -- and
there is a reasonable chance that it won't make this already overdue
release.
In the meantime, here is a workaround that I have sometimes used in other
situations.
Inside your function do the following: fit a new coxph model with fixed
coefficients, and do prediction on that.
myfun - function(oldfit, subset) {
newX - model.matrix(oldfit)[subset,]
newY - oldfit$y[subset]
newfit - coxph(newY ~ newX, iter=0, init=coef(oldfit))
newfit$var - oldfit$var
predict(newfit)
}
If the subset is all of a particular strata, as you indicated, then all of
the predictions will be correct. If not, then those that make use of the
the baseline hazard (type=
expect) will be incorrect but all others are ok.

Hello all! I have a problem with Anova in R and I don't know how to solve that. I want to compute Anova for each experiment (exp). I use this code: test-lapply(split(eg,eg$Exp),function(x) aov(masa.uscat.tr ~ Clona,data = x)) or test-by(eg,eg$Exp, function(x) aov(masa.uscat.tr~Clona,data=x)) I try to compute Tukey HSD test for all Anova for each experiments (Exp) and I want to evaluate model Effects of Anova for each experiment. This are my big problems. thank you! Thank you very much! My data is like this: Exp Plot Clona Prov masa uscat tr masa usc.

I think it'd be easier and safer to save the matrix, either as an .Rdata binary or as a text file, zip that file, and use the sendmailR tools to attach the file to your message.

Re: [R] creating upper triangular matrix
OK, I'm pre-coffee, but what's wrong with using upper.tri to create a new matrix and then multiplying that matrix by the original dat matrix (direct multiplication, not matrix multiply) to get the desired answer?

Re: [R] Sending a matrix in an email
I understand what you are saying. I just didn't think that showing a sendmailR with a matrix as the body of the message would have been very helpful since it is the fact that the received email has no content that is the problem and that would not have shown up in the R console output.

Re: [R] quotation marks and scan
I know you have a solution, but I would have suggested using print() with
quote=FALSE as a better way to illuminate what is going on, as in this
example:
foo - 'bahbah'
foo
[1] bah\bah
print(foo)
[1] bah\bah
print(foo, quote=FALSE)
[1] bahbah
As others said, the backslash isn't really there. So you only have to get
rid of the which you can do with
gsub('','',foo)
[1] bahbah
To summarize, in R, due to its rules for formatting printed output, what
you see isn't always exactly what you have, and this is an example.

No, sorry to flog a dead horse, but you do not appear to get it yet and you really should understand this concept.

Add ylim=c(dataMin, dataMax) to each call to boxplot(), where
you specify values for dataMin and dataMax so their range is
likely to cover all your data. ('ylim', not 'xlim' - the horizontal=TRUE
flips the meaning of 'x' and 'y'.)

[R] Reading in csv data with ff package
I've spent some time trying to wrap my head around reading in large csv files with the ff-package. I think I know how to do it, but am bumping into some problems. I've tried to recreate the issues as best as I can with a smaller example and maybe someone can help explain the problems. The following code just creates a csv file with an integer column, character column and logical column. - library(ff) #Create data size = 2000 fake.data = data.frame(Integer=round(10*runif(size)),Character=sample(LETTERS,size,replace=T),Logical=sample(c(T,F),size,replace=T)) #Write to csv write.csv(fake.data,data.csv,row.names=F) - Now to read it in as a 'ffdf' class, I can do the following: - data = read.csv.ffdf(x=NULL,file=data.csv,nrows=1001,first.rows = 500, next.rows = 1005,sep=,) - That works. But with my current large data set, read.csv.ffdf is debating with me about the classes it's importing. I was also messing around with the first.rows/next.rows, but that's a question for another time. So I'll try to load the data in, specifying the column types (same exact command, except with specifying colClasses): - data = read.csv.ffdf(x=NULL,file=data.csv,nrows=1001,first.rows = 500, next.rows = 1005,sep=,,colClasses = c(integer,integer,logical))Error in scan(file, what, nmax, sep, dec, quote, skip, nlines, na.strings, : scan() expected 'an integer', got 'J' data = read.csv.ffdf(x=NULL,file=data.csv,nrows=1001,first.rows = 500, next.rows = 1005,sep=,,colClasses = c(integer,character,logical))Error in ff(initdata = initdata, length = length, levels = levels, ordered = ordered, : vmode 'character' not implemented data = read.csv.ffdf(x=NULL,file=data.csv,nrows=1001,first.rows = 500, next.rows = 1005,sep=,,colClasses = rep(character,3))Error in ff(initdata = initdata, length = length, levels = levels, ordered = ordered, : vmode 'character' not implemented data = read.csv.ffdf(x=NULL,file=data.csv,nrows=1001,first.rows = 500, next.rows = 1005,sep=,,colClasses = rep(raw,3))Error in scan(file, what, nmax, sep, dec, quote, skip, nlines, na.strings, : scan() expected 'a raw', got '8601' - I just can't find a combination of classes that will result in this reading in. I really don't understand why the classes 'character' won't work for all of them. Any thoughts as to why? I appreciate the help and time.

[R] How can I get seasonal variation table from generalized additive mixed models in R?
Hello everyone, I used a function called gamm in mgcv in R program to investigate seasonal variation of wind speed based on 13 years of measurement dataset. I would like to use this variation in my formula for my study but as I am new in R, it's extremely hard to find values on y-axis.. too many sub-directories of gamm values make me hard to find what directory was actually used for y-axis. My data set is like this below: time /day.of.year/ month /day.of.month /year / WindSpeed 1 17242000 23.429 2 27252000 29.170 3 37262000 16.813 4 47272000 15.271 5 57282000 10.125 6 67292000 13.938 7 77302000 15.854 8 87312000 10.438 9 981 2000 7.125 . .. ... . .. ... As time stamps are separated, I combined all of them first and then ran additive modelling to look at seasonal and yearly trends of 13 years of wind data. My R codes are described below: ballarat - read.csv(ballarat seasonal daily.csv, header=TRUE, sep=,) ballarat1 - within(ballarat, Date - as.Date(paste(year, month, day.of.month, sep = -))) plot(WindSpeed ~ Date, data = ballarat1, type = l) mod - gamm(WindSpeed ~ s(day.of.year, bs = cc) + s(time, bs = cr), data = ballarat1, method = REML, correlation = corAR1(form = ~ 1 | year), knots = list(day.of.year = c(0, 366))) summary(mod$gam) plot(mod$gam, pages = 1) http://i.stack.imgur.com/wU0AU.jpg From the link page of trend graphs, You can see that average wind speed has about +- 2 km/hr variation. I would like to produce tables (two columns (first column: x axis values, second column: y axis (variations)) each day of year) of those two graphs. I assume I need to use gam.predict to get tables of the prediction? As I am new in R, I still can't understand how I can make it work even after reading description of ?gam.predict function. Could you please show me how to do it step by step?

[R] find variation of a binary matrix
Hi: I want to calculate how much the values in a binary matrix varies, and for that I apply the sd() method. mat - matrix(c(1, 1, 1, 1, 1, 1, 0, 0, 0, 0, 1, 1), nrow=4, ncol=3) stddev - sd(dist(mat, method=binary)) And i get the following answer: stddev [1] 0.3442652 Is this correct? Or there is a better way out?

[R] How to convert a 3 dimensional List to make a table with tables tabular()?
I have information in a 3 dimensional list that I want to use to create a table for a written report. The 3d list was created by applying the epiR function epitest to a list of 8 2x2 tables using lapply. The resulting list gives the 12 statistics with CIs, that generated by epitest, for each of the 8 matrices (i9, i10, etc). The list has the following form: Statslow$i9 $aprev est lowerupper 1 0.2263884 0.2244714 0.228314 $tprev est lower upper 1 0.204388 0.2025413 0.2062442 Statslow$i10 $aprev est lowerupper 1 0.227004 0.22545 0.228314 $tprev est lower upper 1 0.204388 0.2025413 0.2062442 I want to create a report that has a table in the following format: I9 i10 Est lower upper Est lower upper aprev 0.23 0.22 0.23 etc tprev0.2 0.20 0.21 etc I have read and tried the tables package pdf and also the information at http://www.r-statistics.com/tag/data-frame/ about cast() and tabular.cast_df.r(), and also all the information I can find on nested tables, but have not be successful.

Re: [R] reshape data frame

Some advice on transforming my data would be appreciated. Attached is an .Rdata image with my examples (reshape_data.frame.Rdata). Within the image are 2 objects: 1) The data object contains an example of my original data format. The columns X20 : X50 are histogram bins, and the rows beneath are the number of observations (ie. counts) within those bins. The other columns; Yr, Seas, Flt.Svy, Gender, Part, NSAMP are observation associated with each bin count. 2) The reshape object is the format I need to transform the data object into. I think the reshape() function is designed for this, and my data object is in wide format, and my resphape object would be in long format. If indeed reshape() is the best way to do this, I'm looking for help in calling the function to transform my data.

Re: [R] Passing parameters in a user defined function to another function using ...
Hi,
It's easy, just carry the arguments in '…' forward to where you expect to pass
them along.
mynumbs-function(x,y,z=5,...){
numbs-sort(sample(y,z, ...))
for (i in 1:(x-1))
numbs-rbind(numbs,sort(sample(y,z, ...)))
print(numbs)
}
Cheers,
Ben

[R] equal horizontal and vertical proportions in graphics
I use several different versions of R, including RGui on Windows and rstudio on Linux. In all cases, I use graphical commands, such as image(). image() displays rectangles, but I want to be able to guarantee that the heights of those rectangles will always equal the widths. Typically, the rectangles come out with notable asymmetries. Thus, if I need to draw a perfect circle with square pixels, I usually get a squashed ellipse with oblong pixels. I have experimented with other commands, and I don't need to continue to use image() if some other command would be more suitable. Thanks.
