"If you can get a vector with all the package names (I do not know how

See ?available.packages
grep-ing the rownames of the available.packages() result appropriately
should give you a vector of the desired package names to install,
which can then be given to install.packages.
... Untested, so no guarantees.
Cheers,
Bert
