[R-SIG-Mac] equivalent of choose.dir()

[Ivan Calandra]

Dear Mac-users,

I have asked on the R list already, but this Mac-list might be more 
appropriate.
I am looking for a function that can choose folders interactively, like 
choose.dir() on Windows, or like file.choose() does for files.

I have found tcltk::tk_choose.dir() but R hangs when I try to do 
anything and I have to force exit.

Jim Holtman proposed to choose a file with file.choose() and then get 
the path from it using dirname(). This approach would work, but it would 
be even better if I could choose a folder directly.

Duncan Murdoch told me that I could write the equivalent of choose.dir() 
for MacOS, but it is beyond my reach.

Can someone help me on this?

Thanks in advance,
Ivan
