[Ivan Calandra]

Thanks Philippe for your answer!
It doesn't work for me, but I guess I have something wrong with Tcl/Tk.

Dear Ivan,

I cannot post to R-help currently. This is something interesting for
you. Could you echo to R-Help and R-SIG-Mac too, please?

You will find a native Mac OS X directory selection dialog box in
svDialogs. Install the package (you also need to install svGUI) and see
?dlgDir.

It works both in R.app and in R run in the terminal. There is just a
little time lag when you call of of svDialogs's dialog boxes the first time.

It works the same on Windows and even on Linux/Unix, providing you have
installed zenity there (search Goggle, installed bty default on Ubuntu,
for instance).
In case the required GUI elements are not found on a particular system,
the function falls back automatically on a textual version at the
terminal. So, it should work everytime!

Don't forget to extract the result from the 'res' element... Something like:

mydir <- dlgDir()$res

Best,

Philippe Grosjean
