And, in addition to the tip from Rui (and similar from Joshua) below,

Hello,
If the files are to be processed in R select a random sample in R.
Using list.files() you can assign a character vector with the filenames
of interest and then sample from that vector.
?list.files
filenames <- list.files(path, pattern)
rand.sampl <- sample(filenames, 45)
Hope this hel

Dear R People:
I am using a Linux system in which I have about 3000 files.
I would like to randomly select about 45 of those files to be processed in R.

This is with R-2.15.1.
Thanks,
erin
