As the posting guide says, there is no such version of R ....

Also, I think you did uninstall a previous version, for it is missing and the default behaviour of the Apple installer is to delete previous versions.

require(ape)
Loading required package: ape
Error in dyn.load(file, DLLpath = DLLpath, ...) :

However when type "library" the packages are there.

Any hints?

Read the documentation: that is not the way to update! But given that you have done so, run

update.packages(checkBuilt = TRUE)

at the R prompt to download and install updated versions of your packages.

We do ask that Mac questions are asked on r-sig-mac, at least if this is for the CRAN distribution of R (there are others, and it is substantially different from building R from the sources for yourself). One of the many things that is non-standard about that distribution is that it hardcodes library paths in its DSOs, so any package with compiled code is tied to a small range (e.g. 2.12.[012]) of R versions.

You will find a lot of discussion about updating in the recent r-sig-mac archives. See also the rw-FAQ at

Many thanks
