It is really a question of the minimal effort needed to learn how to install
the desired package. People will try to to use a tool they already know, then
use the simplest tool. There is an advantage to being able to use the same
tools on more than one platform. R and TeX are a bit different in that many
users rely on them throughout their careers, using multiple platforms or
working with colleagues who use different platforms. A colleague using
Windows says: "you should do (in R): install.packages('hdf5')". When that
fails, that colleague is unlikely to know how to solve the problem.
There is another elephant in this room: security policies are being revised
to require that end-user apps be installed and managed with user privileges.
In practice, large organizations are moving to a model where "root" must have
training/certification, with chargebacks when users need rpm package installs.
At such sites, users are going back to the pre-package days where apps are
installed from sources, or adopting a system like openpkg that uses RPM
packages but can (if used to manage only applications) be used without root
privs. Sooner or later, linux distros will have to deal with this.
