BTW, I found that using things directly in R is _much_
slower than creating a batch file and then running it.
For example, I had a directory with misnamed mp3 files,
and I wanted to use R to rename and copy them
to another directory. I tried to use file.copy, but it
took too much time. Writing a batch file and then running
it was much faster.
