hello,

I'm trying to use R to take an image matrix and paint it into a tcltk canvas. I'm using R-1.9.0 within ess-5.2.0 on a linux machine running the 2.4.30-31.9smp kernel. I'm using the ActiveTcl8.4.6.1-linux-ix86 tcltk libraries.

When I run the following comands, however, I get an R segmentation fault:


> library(tcltk)
> addTclPath("/usr/local/ActiveTcl/lib")
> tclRequire("Img")

<Tcl> 1.3
>tkcmd("image","create","photo",tclVar(),file="/path/to/file.jpg")

Process R segmentation fault at Tue Jul 27 18:18:40 2004



I've run this as root, and I get the same segmentation fault, So I don't think this is a permissions problem. Should I somehow be initializing tclVar()? Can anyone point me to the right way to run this piece of code so that I don't get the segmentation fault?

Thanks in advance.
