[R] capturing output from Win 98 shell

Unfortunately, this does not work and is why I wrote to Rhelp (OK I used
system instead of shell, but I tried shell first); here filenames is
assigned
character(0) even though the dir output is not empty.

Believe me I did read ?shell many times before I wrote: but I am
reporting
that shell does not do what ?shell says it should.

THANK YOU! I'm always forgetting about file.* and friends. Platform
independent too.

Still leaves me asking the bigger question though: how do I capture DOS
command output in general?
