[R-sig-Debian] installing tkrplot

[Mark Leeds]

 Hi All: At the bottom of this email  is my sessionInfo and below that
there is a command
that shows that tcltk is installed and working. My problem is that,  when
trying to install tkrplot,
I get the following  error:

R CMD INSTALL -l . tkrplot_0.0-24.tar.gz

* installing *source* package 'tkrplot' ...
** package 'tkrplot' successfully unpacked and MD5 sums checked

Clearly, I must be missing the tk.h file but I don't know where to get it
nor where to put
it. Thanks a lot.
