Tcl/Tk

Hi Denis,

Was X11 running before you launched R? The error message suggests to
me it wasn't running.

It is extremely unlikely you will need to re-install OS X. Although,
I can imagine you needing to build GRASS from source on your machine
with appropriate configure options to get it to use X11 Tcl/Tk
instead of using Apple's version.

Hi Dan,

I remember now, I had included Tcl/Tk when I installed last time.
Still, I grabbed that straw, downloaded the installer and did a
default install (I checked, it included Tcl/Tk).

However I'm still not out of trouble. I hope I'll find a solution
less disturbing than reinstalling OS X...

This was after a restart immediately following reinstallation of R
2.3.1:

Hi Denis,

For reasons dealing with R's event loop, you need to use X11 Tcl/
Tk rather than the aqua Tcl/Tk version that comes with OS X 10.4
when using Tcl/Tk with R. The CRAN installer of R comes with X11
Tcl/Tk. In terms of how GRASS will behave with X11 Tcl/Tk, I don't
know, but I can imagine bad things if you run both aqua and X11
Tcl/Tk at the same time. The people who most likely will are
Lorenzo Moretti (the address of his GRASS on OS X web site is
http://wwwamb.bologna.enea.it/forgrass/) and William Kyngesburye
(the address of his GRASS on OS X web site is http://
www.kyngchaos.com/macosx/grassinstall).

Hi,

I just tried two things that required Tcl/Tk (acronym I've seen a
lot
lately, but that means next to nothing to me): Grass 6 and R
packages
tcltk and PBSmodelling. Grass simple vanished before completing its
launch, and this is what I got from within R:

library(tcltk)

Loading Tcl/Tk interface ... Erreur dans fun(...) : Can't find a
usable init.tcl in the following directories:
     @TCL_IN_FRAMEWORK@ @TCL_IN_FRAMEWORK@



This probably means that Tcl wasn't installed properly.
Erreur : .onLoad a ?chou? dans 'loadNamespace' pour 'tcltk'
Erreur : le chargement du package / espace de noms a ?chou? pour
'tcltk'

For some reason I thought Tcl/Tk came standard with Tiger. I cannot
find trace of it on my HD. I've used Spotlight but I think this  
does
not search in the invisible folders. I looked manually in /usr and
did not see it, but I could have missed it.

Was I wrong to assume it came with Tiger? Was it like XWindow, a  
box
I had to click to have it included (in which case I'm not sure I
clicked it). I also remember seeing an option for Tcl/Tk when I
installed R 2.3, and I thought I selected it.

Anyway, although answers to the above will satisfy my curiosity, my
main question is: I downloaded TclTkAqua-8.4.10 from
http://sourceforge.net/project/showfiles.php?
group_id=86100&package_id=89343

Can I do any harm in installing this? Is it a solution to the
problems above? Is it the solution you'd recomment?

Thanks in advance,

Denis
