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.
