[R] Saving/loading custom R scripts

[Bert Gunter]

.. Not quite.

?Startup

provides details, but note the comment about only the base package
being loaded and the need to use somepackage::somefunction() or to
explicitly first load a package whose functions are used in .Profile.

Note also that .First could also be used instead of putting the code
in a profile file.
