[R] Anything like dir.choose (similar to file.choose) in R?

2005-08-15 Thread Earl F. Glynn 
Does R have a dir.choose function?

I can use file.choose like this as a kludge to get something like a
dir.choose, but a real dir.choose would be better:

  cat(Select one of files in directory to process:\n)
  filename - gsub(, /, file.choose())
  basepath - dirname(filename)

Windows provides a lower-level SHBrowseForFolder function to create such a
dialog (see links below).  Do other platforms have similar functionality at
a lower level?  (Hoping this would be an easy addition to R.)

If you can use the `tcltk' package, Prof. John Fox had pointed this out to
me before:

dir - tclvalue(tkchooseDirectory())
