[R] iwidgets in tcltk in R 1.7.0

[James Wettenhall]

Hi,

I have successfully installed R 1.7.0 and ActiveTcl 8.4.2.0 in 
Windows 2000.  Yes, I know that Tcl is already bundled with 
R 1.7.0, but I want to use the iwidgets package to create a 
drop-down listbox, and I don't think iwidgets is included in the 
bundled R 1.7.0/TclTk installation package.  I have set the 
environment variables TCL_LIBRARY and MY_TCLTK to the directory 
where I installed ActiveTcl and I have added the Tcl\bin 
directory containing the DLLs to my PATH environment variable.  
I can load the tcltk package with library(tcltk) and use all of 
the standard widgets, but tclRequire("iwidgets") fails :

> tclRequire("iwidgets")
Error in structure(.External("dotTcl", ..., PACKAGE = "tcltk"), 
class = "tclObj") : 
        [tcl] can't find package iwidgets.

Any suggestions would be greatly appreciated.

Thanks,
James
