That is a bit vague.

I currently have R 2.8.0 on a G4 PB running 10.5.7. I don't remember  
that there was a conscious decision not to upgrade R, I also cannot  
remember if I had a reason not to go to OSX 10.5.8. Almost all of my R  
work is on later Macs and the PB now is just for checking PowerPoint  
presentations for compatibility with OpenOffice.

Not sure I know much else to say other than you can get old disk-image  
versions of the universal 32 bit build here:
