[R-SIG-Mac] Installation failed to install GUI

[Bob Harris]

Howdy,

Short description:

I tried to install R 2.2.1, the Power PC version.  I can now run 2.2.1 from 
the terminal app but the GUI did not install.

--- Longer description ---

I have been using R 2.0.1, via the GUI, on my PowerPC OS10.3.9 Mac, but 
today attempted to upgrade this to 2.2.1.  I logged in as an administrator, 
downloaded from the link powerpc/R-2.2.1.dmg at 
cran.r-project.org/bin/macosx/old.  I validated the md5 code, opened the 
.dmg file, the doubled clicked the top-level .mpkg file.

During install, it claimed it was going to install R.app in my applications 
folder.  However, no such file or folder is to be found.  I realize that it 
will appear in the finder as just plain R.  I have manually hunted for it, 
and have also used the finder's find function to search for it.  I note that 
the read-me-type info shown during installation describes a couple of the 
*other* packages as "optional" but provides no means to choose or not choose 
them.

The command-line r runs from the terminal window, which I presume means that 
the framework version installed OK.

The .dmg file has a subfolder called packages so I looked in there and saw 
four .pkg files, one of which was R-GUI.pkg.  Grasping at straws, I 
double-clicked on this and it brought up the installer.  Unfortunately, when 
it came to the panel which allows me to elect the destination folder, it 
marked my hard drive with a red exclamation point at grayed out the buttons 
that would allow me to choose a destination folder.

Please help.  I use R on a regular basis for my research (I'm a PhD 
student).  I regret having attempted to upgrade, because I have now lost the 
ability to use R at all.

--- Even longer description ---

The reason for attempting to upgrade was a difference I was seeing in the 
results from ks.test in R version 2.0.1 on my machine, vs R version 2.2.1 
accessed from RPy, on a different machine (the latter occasionally reports 
negative probabilities which is not a good sign).  In attempting to chase 
down that problem, I thought it would be a good idea to try 2.2.1 without 
RPy so I could isolate whether the problem was in RPy or R.

The reason I chose 2.2.1 instead of a newer version is twofold.  First, I 
wanted to compare results to the version 2.2.1 running on another machine.  
Second, I am running OSX 10.3.9, and am not interested in attempting to 
upgrade to 10.4.X at the moment.  The download page advises me that I can 
build the latest version from the source code, but I've been down that path 
before on three Macs and have never been anywhere close to successful.

Thanks for any help,
Bob H
