[R] Storing user-defined R functions

[David.Epstein]

Thanks to everyone for writing. A well-known phenomenon in mathematics,
statistics and/or complex computing is that everything one already knows
feels trivial and easy. It's as though one is permanently climbing a
vertical cliff-face, while, if you look back from where you've come, you see
a level plateau just a couple of inches lower than one's boots. I take
statements about how easy it is to make packages with a pinch of salt---I'm
sure it's easy when you already know how.

I've been looking through 
http://127.0.0.1:31257/doc/manual/R-exts.html#Creating-R-packages
http://127.0.0.1:31257/doc/manual/R-exts.html#Creating-R-packages  with a
mixture of bafflement and horror. Even to skim this document without
understanding all that much of it would take me a couple of hours. To make
my first package might take me a couple of days, or maybe longer.

To follow David Scott's suggestion would take me 5 minutes max.

And I have a huge workload with looming deadlines ....

It might be different if there were a "Dummies' guide to packages", allowing
one to rapidly assemble a
a few easy functions, and omitting all the optional features---a guide to
the first steps up the cliff-face. If there is a Dummies' guide, I would be
glad to hear of it.

David
