This is relatively simple if you can find the packages you need in the
default Tcl/Tk install on the Mac (/System/Library/Tcl) and if these
packages are compatibles with the X11 Tcl/Tk used by R. This should be
fine for packages containing no compiled code. For the others, you
should check first (but for instance, Img and tsl work for me - Mac OS X
10.6.4). You can then use these package in R own Tcl environment like this:
> library(tcltk)
Loading Tcl/Tk interface ... done
> addTclPath("/System/Library/Tcl")
> tclRequire("Img")
<Tcl> 1.4
