Hi Erin, It is not difficult to imagine doing it either in R or via the shell. If they are all in the same directory, I would tend towards R, just because you can easily set the seed and keep that information so you can reproduce your random selection.
If the wd is in the directory with the files, from R just: set.seed(10) toprocess <- sample(list.files(), size = 45) Cheers, Josh On Sat, Jul 28, 2012 at 10:49 AM, Erin Hodgess <erinm.hodg...@gmail.com> wrote: > 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. > > Could I make the selection in R or should I do it in Linux, please? > > This is with R-2.15.1. > > Thanks, > erin > > > -- > Erin Hodgess > Associate Professor > Department of Computer and Mathematical Sciences > University of Houston - Downtown > mailto: erinm.hodg...@gmail.com > > ______________________________________________ > R-help@r-project.org mailing list > https://stat.ethz.ch/mailman/listinfo/r-help > PLEASE do read the posting guide http://www.R-project.org/posting-guide.html > and provide commented, minimal, self-contained, reproducible code. -- Joshua Wiley Ph.D. Student, Health Psychology Programmer Analyst II, Statistical Consulting Group University of California, Los Angeles https://joshuawiley.com/ ______________________________________________ R-help@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide http://www.R-project.org/posting-guide.html and provide commented, minimal, self-contained, reproducible code.
