I would like to install two versions of R on Mac OSX 10.6.7.
The two versions I would like to install are 2.10.1 and 12.2.2 for use with
StatET in Eclipse. I have successfully installed and used each version
respectively with StatET in Eclipse. However, I have not been successful in
getting both of them configured for use on the same system.
We know from the Read Me during the .pkg installation that R will over write
older versions. The installer recommends running:
pkgutil --forget org.r-project.R.Leopard.fw.pkg
to keep the previous versions. In addition, a reply (Mon Feb 9 15:31:19 CET
2009) to a similar question in this form recommends using
pkuntils --pkgs | grep r-project
I "believe" that both of these commands run successfully. However, the next
installation of R still over-writes the previous version.
The (Mon Feb 9 15:31:19 CET 2009) post also states to delete:
./Library/Receipts/R-Frameworks.pkg
However, neither 2.10.1 or 12.2.2 create a R-Frameworks.pkg in
./Library/Receipts/.
I would be genuinely interested in obtaining detailed and organized
instructions on how to successfully install two versions of R on the same
system.
It would also be great if those instructions were written in such a way that a
user with limited Linux experience could understand and implement them.
Best,
Justin
