R help - Oct 2009 - tk_choose.files without multiple selection?

Dear all,
 
I compared tk_choose.files on linux with choose.files or tk_choose.files on
windows and found that tk_choose.files does not allow multiple selection on
linux - independent on keyword setting "multi".

file(s)")
On linux I get the error message:
    File <list of selected filenames> does not exist.
I have to click "cancel" to get out of the dialog.
Any ideas?

Regards

This depends on the version of Tk you have installed.  The Tk 8.5.7
ChangeLog has

2008-08-25  Todd M. Helfter <tmh at users.sourceforge.net>

         The patch is associated with the bug tracker id: 1936220
         library/tkfbox.tcl : fix the multiple selection error for
         tk_getOpenFile -multiple 1 which fails on all unix platforms since
         the adoption of ttk widgets.

for just after 8.5.4.

So I suggest you update your OS's Tcl/Tk if it is older than that 
(and that fix is 14 months old, so one would hope that your OS has 
updates available).

R for Windows ships with 8.5.6, R for Mac OS X with 8.5.5.
