Thanks for your reply Peter.

I have tried many case variations, but none worked.

What TCL command would you suggest (I am no expert in TCL)?

I also tried to load IWidgets, but now, loading doesn't work !

> library(tcltk)
> addTclPath("C:/TCL/LIB/IWIDGETS4.0.2")
> tclRequire("IWidgets")
Error in structure(.External("dotTcl", ..., PACKAGE = "tcltk"), class = "tclObj") : 
        [tcl] can't find package IWidgets.

again when varying lower/upper case.

I would like to use one of these to write a simple TCLTK interface to R for my students.
