[R] Loading tcltk package fails on WinMe/Cygwin but works with Rgui

[christian]

...i can only suggest  that  now tcl/tk & win2000 works fine with
this row in  file   /etc/Rprofile
Sys.putenv("TCL_LIBRARY"="c:/develope/Tcl/lib/tcl8.3")

and it is possible to test the entry in R with:
Sys.getenv()


                   TCL_LIBRARY 
                                                                                                                                                                                                                                 
"c:/develope/Tcl/lib/tcl8.3"
