[R] Help with TCL packages

I am exploring the TCLTK package under R and try to load and use additional TCL libraries (under Windows, with TCL8.3). For example :

> addTclPath("C:/TCL/lib/bwidget1.5")
> tclRequire("BWidget")
<Tcl> 1.5

Loading seems to work, but when I try to create a specific widget :

# The main window appears correctly
> top=tktoplevel()

# Trying to insert a combobox
> combo <- tkwidget(top,"BWidget::combobox")
Error in structure(.External("dotTcl", ..., PACKAGE = "tcltk"), class = "tclObj") : 
        [tcl] invalid command name "BWidget::combobox".

The file combobox.tcl is present in the BWidget directory.

I wonder what I'm doing wrong. Any idea ?
