R is certainly not the natural tool you would use for this, but with effort it
could be done, I think.
dir(..., recursive = TRUE)
will list files descending down a directory tree. You may then need to use
things like basename() to strip off the directory names, grep() to search for
the keyword, setdiff(..,..) to find which are missing, file.copy() to do the
copying.
This is probably not the usual entry point to R, though.

Subject: [R] Finding and moving files
Hi!
I'm at the very beggining of my R experience and I'm hoping someone can
point me in the right direction. I want to create a script that locates all
files within a directory tree that have certain keywords in their file
names, checks these against files in another location, then copies files
that don't already exist in that other location.
I'm currently tralling through the help reference but I've yet to find
anything that might do the trick. Any ideas?
Thanks!
Dan
