Globbing Files in R

Try this:

file.names <- dir(pattern = glob2rx("/mydir/*.txt"))
for(fn in file.names) {
  DF <- read.table(fn, ...)
  ...
}

Another possibility is:

file.names <- .. as above ...
out <- lapply(file.names, function(fn) {
   DF <- read.table(fn, ...)
   ...
})

out will have one component per file formed from the result of the
each function application.

Dear all,

For example I want to process set of files.

Typically  Perl's idiom would be:

__BEGIN__
@files = glob("/mydir/*.txt");

foreach my $file (@files) {
 # process the file
}
__END__

What's the R's way to do that?
