Tcltk hangs when I invoke RCommander

Dear all,

As a slight addendum, I intend in future to recommend that the Rcmdr be
installed with install.packages("Rcmdr") and then to let it install its own
dependencies on first use; with the current version of the Rcmdr package,
this will cut down on the number of packages installed.

Best,
 John

Dear Andy and Simon,

There are installation notes for Mac users of the R Commander at
<http://socserv.socsci.mcmaster.ca/jfox/Misc/Rcmdr/installation-notes.
html

If after following the steps in the installation notes the Rcmdr still
fails to work, I too would be interested to find that out.

The second step in those directions was my guess as to the lesion. My
understanding is that in 10.5 and 10.6 X11 is a default installation.

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:

invisible(structure(msg, class = "try-error"))})
14: try(gsub("\\s+", " ", paste(capture.output(print(args(help))),
collapse = "")), silent = TRUE)

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!
