[Rd] Installing a Tcl/Tk Extension on OSX

[Philippe Grosjean]

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

Best,

Philippe
