You can run a single R command from the command line using the -e option, so

R -e "brew::brew('featurefull.brew')"

(or some variation on that, depending on how your shell handles quotes) 
will run that one command.  Use R --help to see other options, e.g. to 
suppress the banner, etc.

It shouldn't be too hard to work out how to construct that line from 
your favourite shell scripting language, so

brew featurefull.brew

would execute it.
