column selection for aggregate()
Hi everybody! I'm working on R today so I have a lot of questions (you may have noticed that it's the 3rd email today). I'm new on R, so please excuse the "spam"! I have a dataset "ssfa" with many rows and the column names are: > names(ssfa) [1] "SPECSHOR" "BONE" "TO_POS" "MEASUREM" "FACETTE"

loop on list levels and names
Hi everybody! To use some functions, I have to transform my dataset into a list, where each element contains one group, and I have to prepare a list for each variable I have (altogether I have 15 variables, and many entries per factor level) Here is some part of my dataset: SPECSHOR BONE Asfc Smc epLsar cotau tx 454.390369 29.261638 0.001136 cotau tx 117.445711

Illustrating kernel distribution in wheat ears
Dear all R2.10 WinXP I have a dataset dealing with the way different wheat cultivars build their yield. Wheat ears are organised in spikelets where the spikelets can be numbered from the bottom, with even numbers on one side and odd on the other. I know how many kernels there were in each spikelet after some months spent counting them... Now I want to illustrate the differences between the

export test results to csv
Hi everybody! I would like to export the results of a test statistic in a *.csv file, but get an error. The code is below. The data are attached as .txt with tab as separator. I tried to get a sample dataset, but for some reason it didn't work, so please excuse the length of the file. I also attached a txt with the output (copy/paste) in case that helps. ---- > library(WRS) >

R versions and PostScript files
Dear R users, I have a desktop computer and a laptop, both of them with Ubuntu Lucid. The former has R2.10 installed from Ubuntu repositories (this is the most recent version in the repositories), while the latter has R2.13 from the CRAN repositories. I noticed that postscript files generated with R2.10 are "better" than files generated with the latest release of R, in particular for

R takes long time to open
Hello. Until today I've been using R2.9 and since today R2.10 (on a PC). In both of them it takes about 20 sec for the prompt to appear IN R console after I start R. And every time it says: "Previous saved work space restored" - even if I have not saved any workspace or, in case of R2.10 - even though I have not used it once. In the older versions - R would start within 2-3 sec. Is

speed up process
Dear users, I have a double for loop that does exactly what I want, but is quite slow. It is not so much with this simplified example, but IRL it is slow. Can anyone help me improve it? The data and code for foo_reg() are available at the end of the email; I preferred going directly into the problematic part. Here is the code (I tried to simplify it but I cannot do it too much or else it

"\n" in legend using substitute and as.expression

Changing x-axis on boxplot
Dear List, ? I am creating a boxplot with two subsets, very similar to the example by Roger Bivand at ?boxplot (reproduced below).? I am trying to change the labels on the x-axis to have one number to cover both subsets.? I can do this in other plots by using axis=FALSE followed by a separate axis() command.? I have also tried variations in the names= argument but can't get it to work.?

Again, about boxplot
Thank you for your guys reply for my previous question. But I got one more question about the boxplot. With the code in the R-help: boxplot(len ~ dose, data = ToothGrowth, boxwex = 0.25, at = 1:3 - 0.2, subset = supp == "VC", col = "yellow", main = "Guinea Pigs' Tooth Growth", xlab = "Vitamin C dose mg", ylab =

unique function works funny
I have 3 nested functions, the core function goes like this: listx<-function(x,tox) { xt=table(x) wa=sort(unique(x,fromLast=FALSE)) print(xt) print(wa) ...... return(kk) } listx get called in functionB, and functionB get called in functionC. When I test functionB, the listx function works just fine. When I call functionB from functionC, strange thing happened: My result for xt: 0.07 0.17

export graphics for editing in Illustrator
Dear R users, I would like to edit my graphics in Illustrator. I know that I can set up almost every graph parameter in R, but the time I will spend searching for the correct settings might not be worth since I'm quite used to Illustrator and since I will in any case use Illustrator to prepare for publication. Up to now, I've used savePlot() with type=("eps") but I'm

Installing packages, again
Hi again, I've just uninstalled R2.01 and installed the new R2.10 on my WindowsXP machine. I then attempted to install the vegan package from source files, as I learned to do last week, with the help of some of you. I have updated my path variable to the new R directory (R/rw2010/bin instead of R/rw2001pat/bin), and I've still got the HTMLHelpWorkshop files installed, as well as Perl

export tables to Excel files
Dear R users, I've just posted a similar question about Illustrator. This time I would like to export the results of my statistic tables and my dataframes into Excel files. Up to now I've used write.csv(), but I have to resave every file in .xls in Excel. I would like to know if there is a function or package to export directly into *.xls. I have found xlsReadWrite which would be

Labelling boxplot with fivenumber summary
I am very new to R so forgive me if this seems basic but I have done extensive searching and failed to come up with the answer for myself. I am trying to label a boxplot I have created with the values for the median, upper and lower quartiles and max and min values. I have been unable to do this or find anything on the net to say how it might be done. Is this possible and if so how? Regards,

Help function "?" in R 2.10.1
Hello everyone, I have versions 2.7.2 and 2.10.1 installed on a machine that has no access to internet.

Have I downloaded 2.10.1 incorrectly (=forgot to tick some box for local help file repository) or is the internet help now the
