Subject: Re: [R-SIG-Mac] Tcltk hangs when I invoke RCommander
Andy,
please check that you have X11 installed. Also see whether clicking
on
the X11 icon in the GUI toolbar does start X11. Finally, try setting
Sys.setenv(DISPLAY=":0.0")
before loading tcltk/Rcmdr.
If that doesn't help, please send me the crash log.
Thanks,
Simon

Upon invoking library(Rcmdr) , I get the notice that tcltk is being
called up followed by a system prompt (>). However, the X11 window
doesn't open, and nothing at all happens. When I type any legitimate
command at the prompt, this appears in the R Console window:

Possible actions:
1: abort (with core dump, if enabled)
2: normal R exit
3: exit R without saving workspace
4: exit R saving workspace
I've forwarded the entire core dump to Apple and have a copy of it
but
have no idea how to make sense of it.
Odd thing is, this problem doesn't occur on my 2008 Macbook at home,
which runs the same Mac OS. It's peculiar to the iMac at my
worksite.
As I'm hoping to use R in some of my advanced undergrad teaching,
it'll be helpful to solve this problem so my students can take
advantage of the RCommander GUI.
Thanks for any light you can shed on this!
