Dear John,
i did follow the Rcmdr instructions for macosx, having no results
though.
I am soon upgrading to 10.5 and hope i'll encounter no problems.
The silly thing however was that i had installed every file needed
for rcmdr to run but apparently had no results.

Is there maybe some key point which is usually forgotten, more than
what i have done (descripted below)?
I'm afraid that I can't offer much more help, since, as I explained, I'm a
relatively new Mac user myself. If you've followed all of the steps in the
directions, then you haven't left anything out. You don't really say in much
detail that you've done. For example, did you click the "X" button in the R
Console?
From the instructions:
4) Start R (e.g. double-click the R icon in /Applications).
5) Start X11 (e.g. click the X11 button on the R Console or double-click the
X11 icon in /Applications/Utilities).
6) Close the X11 terminal (optional).
7) Type library(Rcmdr) in the R Console and press Return.

Also when you installed R, did you attend to:

1) Install R.app (the R for Mac OS X GUI). If you select 'Customize' during
installation of R.app, make sure the entry for tcltk remains selected.

One more thing that you could do would be to answer the question that I
asked you in my last email: What happens when you try to load the tcltk
package directly via library(tcltk)?
Ben

p.s. i am also attaching Chiara to this email who is providing
assistance to the research and is struggling with Rcmdr on her laptop.
Is Chiara a Mac user too? What problem is she encountering?

Regards,
 John

Dear Ben,

It seems clear that the problem is in loading the tcltk package. To
confirm
that, does library(tcltk) fail?

I'm not very knowledgeable about Mac OS X. I do have a MacBook,
with OS X
10.5, however, and encountered no problems installing and running
the Rcmdr
package. Have you seen the R Commander installation instructions
for Mac OS
X 10.4, at
<http://socserv.mcmaster.ca/jfox/Misc/Rcmdr/installation-
notes.html>? If
not, maybe something there will help.

I'm copying this response to Rob Goedman <goedman at mac.com>, who has
provided
help before.

Regards,
 John

Hello everyone,

i have been searching the whole day, trying ANY solution offered
by the
internet and before headbanging against the wall would like to try
asking
for your help.

As many others, i am haveing problems loading the Rcmdr package with
Macbook
running Tiger 10.4.11. X11 version updated to the last one after
having
manually installed.

I have also installed (obviously) the Rcmdr package with all
dependencies.

However (damn) i keep having the following answer to the library
(rcmdr)
command:

library (Rcmdr)
Carico il pacchetto richiesto: tcltk
Loading Tcl/Tk interface ... Error in dyn.load(file, DLLpath =
DLLpath,
...)
:
  impossibile caricare libreria condivisa

'/Library/Frameworks/R.framework/Versions/2.8/Resources/library/
tcltk/libs/i
3
86/tcltk.so':

dlopen(/Library/Frameworks/R.framework/Versions/2.8/Resources/
library/tcltk/
l
ibs/i386/tcltk.so,
10): Library not loaded: /usr/local/lib/libtcl8.5.dylib
  Referenced from:

/Library/Frameworks/R.framework/Versions/2.8/Resources/library/
tcltk/libs/i3
8
6/tcltk.so
  Reason: image not found
Error : .onLoad non riuscito in 'loadNamespace' per tcltk
Errore: pacchetto 'tcltk' non caricato

The language is in italian but it basically says it cannot load
shared
library.

x11 is running, the file tcltk.so phisically exists (i have checked
myself)
and both R and X11 are in their last updated version.

I have also tried restarting after updating X11. Can someone try
to help
me?
i have recently swithced to mac and am having an important exam soon.

Thanks to anyone.

Ben
