iterating over files in a directory with R
Try help("list.files"), help("file.info"), help("file"), and
look in the "see also" section in each of those help files for
other functions which you may find useful for doing this.

Hello,
I'm an R newbie and was wondering whether there are R commands for iterating over files in a directory. Basically what I want to do is to iterate over many files and apply some R functions to each file seperately.
e.g. for (each file in a directory) do { some R calculation with the info in that file }
Could someone please give me a pointer to how (or if) this might be done with R - I haven't yet been able to find anything relevant in the manuals. Or would I need to call each file with some language such as Java and then use R once I have the file name?
Thanks for your help,
femke
