[R] is there a way to update both packages if they occur in 2 libraries?

[Uwe Ligges]

update.packages() updates all packages in all libraries listed in 
.libPaths() unless you specify an explicit library.

It may happen that the version number has not changed and you just want 
to reinstall for your upgraded R. In that case use:

update.packages(checkBuilt=TRUE)

Best,
Uwe Ligges
