I'm not sure what you mean by that.  Of course they do run under
Command Prompt, but the limitations of the command window are so
severe that almost nobody ever does that, they click on an icon to
start.  Nevertheless the basic interactions that are always available
are command-shell-like (as in IDLE), although there are icon- or menu-
driven GUI shells or modes available for each.

In Emacs, the basic interface is the "list-packages" command, which
brings up a (text) menu of installed and available packages on the
ELPA package repository.  In R, it's the package.install() function,
which I think has a subfeature that will list the packages available
from the CRAN package repository (but I always just go to the
website).
