Answer 1

You mention that you don't want to shell out to a Linux/UNIX command but I assume its ok to shell out to a Windows command. In that case this would do it:

shell("dir/ad/b", intern = TRUE)

and this would do it recursively:

shell("dir/ad/b/s", intern = TRUE)

Normally I would prefer the platform independent solutions of others here but particularly for interactive use where you are just concerned with getting the answer as simply and directly as possible this may be less work.
