Re: [R] Boxplot of multiple vectors with different lengths
Ryan, I think you could do what you want by having the vector data written to separate files; then create a file containing the individual file names. In R, read the file containing the list of file names and loop through this reading in the individual vector files. Maybe this is an inelegant, brute force approach, but it has worked for me with essentially the same problem.

Re: [R] Boxplot of multiple vectors with different lengths
Sorry -- previous versiuon prematurely sent. Full version is: Yikes! You should never have to do this sort of thing (writing stuff out to files, etc.) What is wanted, I believe, is ?do.call as in do.call(boxplot, z) where z is list(a,b,c) as Sarah described. However, I think you might do even better in terms of controlling options, labels, etc. if you would get the data into standard flat file format (data frame) as Result Source 1a 3 b 2 b 5 c ... etc. (This is easy to do in R and via many packages.) and then use he formula interface in the lattice ?bwplot function for th eplot.

Re: [R] Boxplot of multiple vectors with different lengths
Bert, I may be mistaken, but I thought Ryan wrote write code that automatically *imports data* from different files (with different lengths-just one variable), so, I was referring to doing something with the data before it gets into R. I understand that one should not need to write out data and then re-read it in some way. As I said, those more experienced with R will probably offer better ideas.

I understand that one should not need to write out data and then re-read it in some way. As I said, those more experienced with R will probably offer better ideas.

You should never have to do this sort of thing (writing stuff out to files, etc.) What is wanted, I believe, is ?do.call as in do.call(boxplot, z) where z is list(a,b,c) as Sarah described. However, I think you might do even better in terms of controlling options, labels, etc. if you would get the data into standard flat file format (data frame) as Result Source 1 a 3 b 2 b 5 c ... etc. (This is easy to do in R and via many packages.) and then use he formula interface in the lattice ?bwplot function for th eplot.

In R, read the file containing the list of file names and loop through this reading in the individual vector files. Maybe this is an inelegant, brute force approach, but it has worked for me with essentially the same problem.

Re: [R] Boxplot of multiple vectors with different lengths
If you have already made numeric vectors called a, b, and c a - 1:10 b - sqrt(1:200) c - log2(1:500) and a character vector z containing their names z - c(a, b, c) then make a list containing the data with them with dataList - lapply(z, get, envir=environment()) names(dataList) - z and make your boxplots with boxplot(dataList) Then forget about using the variables a, b, and c and use dataList[[a]], dataList[[b]], etc. instead. You may want to use a shorter name than dataList.
