I *assume* that I'm using "the official ppa", but I have no idea what that means!!! Can you elaborate? Can you also elaborate as to how to "uninstall the newer versions"? Sorry to be so demanding and to be such a thicko. > If all you need is R 4.1.0, this might be a bit less temperamental. There is a problem however. I really want to have 4.1.0 *available*, but to keep 4.1.1 as being the "real" R. If I were to succeed in "installing" from source, I could do just the configure/make steps and omit the "make install" step. I could then run R 4.1.0 from the bin directory that is created. I think! Rather than putting the executable into /usr/bin, so that /usr/bin/R would remain the 4.1.1 version. Is there any way/can you see any way to have both the 4.1.1 and the 4.1.0 versions available, when the 4.1.0 version is installed from binary in the manner that you suggest? Again, sorry to be so demanding and to be such a thicko. cheers, Rolf -- Honorary Research Fellow Department of Statistics University of Auckland Phone: +64-9-373-7599 ext. 88276 _______________________________________________ R-SIG-Debian mailing list R-SIG-Debian@r-project.org https://stat.ethz.ch/mailman/listinfo/r-sig-debian
