I have Windows XP build scripts that look for R in a variety of folders and if multiple ones are found, takes the last one. For example, I currently have the following in \Program Files\R : rw1060 rw1062 rw1071 rw1071beta rw1081 rw1090 rw1090dev rw1091 rw1091pat rw2000 rw2001beta Note that it currently correctly gets rw2001beta but if I add rw2001 then it will not pick it up since

Hello, When building my package (R CMD check) following error message occurs: ... varinf.plot text html latex example x text html latex example make[2]: *** No rule to make target `disclosure.chm`. Stop. cp: cannot stat 'D:/Programme/R/rw2010dev/disclosure/chm/disclosure.chm`: No such file or directory make[1]: *** [chm-disclosure] Error 1 make: ***

Hi all, I'm seeing an error on Windows when I try to install a package to a package library path that starts with a digit. I can reproduce the error as follows using R-devel from Feb 24 on Windows advanced server: badLib = "c:\\badExample\\2\\foo" dir.create(badLib, recursive=TRUE) z = .libPaths() z = .libPaths(c(badLib, z)) z [1] "c:\\badExample\\2\\foo"

Consider the following example: # substitute a with b in the indicated function. Seems to work. > z <- substitute( function()a+1, list(a=quote(b)) ) > z function() b + 1 # z is an object of class call so use eval # to turn it into an object of class expression; however, # when z is evaluated, the variable a returns. > eval(z) function()a+1 Why did a suddenly reappear again

I tried it using file and it seems to work for saving: > data(iris) > con <- file("clipboard","w") > save(iris,ascii=T,file=con) > close(con) > readLines("clipboard") ... lengthy output follows which seems correct ... but not for loading: > con <- file("clipboard","r") > load(con) Error in load(con) : loading from

Hi, is checking out R SVN trunk the recommended way to keep up to date with R-devel and check packages with the latest version? My objective is to be able to have both R and R-devel versions installed/working and up to date. R-devel binaries would be available as symlinks in my home directory so that I can do: Rdevel CMD check mypkg Rdscript -e "some R code" anywhere on my system.

Hi I'm using R 2.0 in SuSE 9.2. When I plot data as a boxplot, the boxes appear on the plot in alphabetical order (of group) rather than the order in which they appear in the data. So far, the only thing I can do to fix this is to prefix the group labels with a,b,c...etc to trick R into plotting them in the right order. Can sorting be turned off? How should I address this sensibly? Thanks

Hi, if we have a file called Rscript.R that contains the following, for example: x <- 1:100 outfile = "Rscript.Rout" sink(outfile) print(x) and then we run >> source("Rscript.R") we get an output file called Rscript.Rout - great! Is there an internal variable, something like .Platform, that holds the script name when it is being executed? I would like to use

Hi, Are there labeled break statements in R? i.e., something along the lines of TOPLOOP: for(i in 1:m) { for(j in 1:n) { ... if(condition) { break TOPLOOP } } } Thanks, Roger

One can perform a for loop without indices over the columns of a dataframe like this: for( v in df ) ... some statements involving v ... Is there some way to do this for rows other than using indices: for( i in 1:nrow(df) ) ... some statements involving df[i,] ... If the dataframe had only numeric entries I could transpose it and then do it over columns but what about the general case?

With rw2010dev I get a strange protect(): protection stack overflow error with a small data frame which otherwise is usable: If anybody wants to have a look I can provide an RData file with the problematic data frame. Doesn't seem to be necessary, the following simulated example generates the error: > testmat <- matrix(1:80, 20,4) > dim(testmat) [1] 20 4 > str(testmat) int

I have Excel files containing data that I would like to move to R. They are in the standard form of a one row header followed by rows of data, one record per row EXCEPT that there are a few rows of comments before the header. The number of rows of comments varies. For Excel files of this form without comments I have had success with: require(RODBC) z <-

When I alter the levels of a factor, why does it alter the names too? f <- factor(c(A="one",B="two",C="one",D="one",E="three"), levels=c("one","two","three")) names(f) -- gives [1] "A" "B" "C" "D" "E" levels(f) <-

In ?exists it says: inherits: should the enclosing frames of the environment be searched? I believe what it is saying is that if inherits is TRUE and it fails to find the variable it will look in the parent environment and the parent of the parent, etc. (as opposed to looking in the calling frame next and the caller of the caller, etc.) Now I thought that standard terminology in R was: 1.

Hi, I have simple R question. I have a vector x that contains real numbers. I would like to create another vector col that is the same length of x such that: if x[i] < 250 then col[i] = "red" else if x[i] < 500 then col[i] = "blue" else if x[i] < 750 then col[i] = "green" else col[i] = "black" for all i I am convinced that there is probably a

Hello, Pass by reference appears to be a topic which comes up from time to time, but I wasn't able to find something in the R-help archives which tells how to accomplish it. I have a problem that you may have seen before -- R runs out of memory when processing large matrices. Part of the problem for me is that I am using some large matrices as function arguments, and these are modified,

Dear R people, I have a very big tab-delim txt file with header and I only want to import several columns into R. I checked the options for "read.table" and only found "nrows" which lets you specify the maximum number of rows to read in. Although I can use some text editors (e.g., wordpad) to edit the txt file first before running R, I feel it?s not very convenient. The
