I'm using R on Windows and wondering if there is an R package that allows
you to do folder structure analysis.
Specifically, I would like to grab the name, file size, type, and creation data
of files within a folder and then to means and sigmas on the file size and
creationdation date.
Thank you again for your insights.

However, you don't really need to go even that far. Recent versions of R have tab completion. So take a guess as to what function might help you out, type the first few characters, then hit tab once (or maybe twice) and see what pops up. Then put a '?' in front of that function name and check the help page. Using some of the words in your 'Specifically, ...' sentence, I tried this. Some of them did not complete, some completed but were obviously not what you were after, and some were highly suggestive. Oh yes, one led to a function that seemed like an obvious winner and the example on its help page comes very close to solving your problem. Enjoy!
