If you:
- use Linux
- have just upgraded your R installation from 2.12 to 2.13
- installed some/all of your packages in your home area (e.g. ~/R/i486-pc-linux-gnu-library/2.12) and…
- …are wondering why R can’t see them any more
just do this:
# at a shell prompt cp -r ~/R/i486-pc-linux-gnu-library/2.12 ~/R/i486-pc-linux-gnu-library/2.13 # in R console update.packages(checkBuilt=TRUE, ask=FALSE) # back to the shell rm -rf ~/R/i486-pc-linux-gnu-library/2.12
update: corrected a typo; of course you need “cp -r”
