The dir function
Sys.glob is much more direct

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 f

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?
