I'm running Debian Squeeze on an amd64 machine and currently have R 2.15.3. Some packages have been installed with aptitude and some with install.packages(). Now I'd like to update R to 3.0.2 (I upgraded arm to a version that requires 3.0 :-( ), and I'm a confused.
- http://cran.us.r-project.org/bin/linux/debian/ seems to say I just change the sources list to point to '...cran3' instead of to '...cran' and then update / upgrade. Yet http://cran.r-project.org/bin/windows/base/rw-FAQ.html#What_0027s-the-best-way-to-upgrade_003f (admittedly for Windows) says to uninstall and reinstall R. Do I follow the cran -> cran3 update approach, as I'm on Linux? - http://cran.us.r-project.org/bin/linux/debian/ says I should run "`dpkg -get-selections | grep r-cran` and compare with the list of packages supported below." I've done that, but I don't know what to do with that knowledge: do I `aptitude remove` all of those packages /not/ listed below or do something else? - http://www.r-bloggers.com/upgrading-r-and-packages/ suggests a script that updates installed packages. I've used that on minor upgrades on XP successfully. I don't see documentation that suggests it's needed for major upgrades or perhaps on Linux. http://www.r-bloggers.com/r-3-0-0-is-released-whats-new-and-how-to-upgrade/ seems to suggest that running `update.packages(checkBuilt=TRUE)` is sufficient (except perhaps for what aptitude has to do). What is the right thing to do? If the answers to those three questions aren't simple, are there explicit, step-by-step instructions somewhere? I've looked unsuccessfully. Is this a fairly foolproof upgrade? Minor upgrades have certainly seemed simple on both Linux and Windows. Thanks, Bill PS: I'll also have to upgrade a Windows installation soon. I'm running 2.15.3 under XP64 on one machine and under XP on another, and both will get new installations of W7 after the disks are wiped. Is there a neat way to reinstall all the packages I currently have when I reinstall R (version 3.0.2 on W7)? -- Bill Harris Facilitated Systems http://makingsense.facilitatedsystems.com/ _______________________________________________ R-SIG-Debian mailing list [email protected] https://stat.ethz.ch/mailman/listinfo/r-sig-debian
