Er, in what sense is Solaris not a Unix variant??? Or did you refer to
Geldenhuys being on W95?

Anyways, Guido Masarotto has a nice little "proof of concept" thing on
how to set things up so that you can call R commands directly from
Tcl/Tk code. You may want to check it out. 

[There's a silly bug (in glibc) preventing it from working
on Linux machines (at least RedHat5.2) if you use localization
features (LC_CTYPE & friends), but that's probably getting cleaned up
in the near future with glibc 2.1, and perhaps portability need not
concern you for now]
