[R] Windows List of Folders?

[khobson@fd9ns01.okladot.state.ok.us]

For windows, how can I list only the folders in some folder?
I was thinking that dir() and file.info() with isdir==TRUE being something
that might work.

These folders or directories are numerically named with no dot extension
names or other characters.  Typically, these are 3132, 3334, ...

Here is what I tried.  The last line is where I need more work.

pData="C:/Myfiles/R/Data/"
setwd (pData)
x <- dir(pData, all.files=F)
y <- file.info(x, x$isdir==T)

TIA
