identical function names from 2 packages
...ad 2 packages that have a function with the same
name, how do I tell R to run one or the other?
(Instead of having R automatically use the first- or
last-loaded one, whichever it is. (Which is it, by the way.))
Cheers!

Is there a hidden variable somewhere that stores the result, so that one
doesn't have to re-run the analysis for an hour?
E.g., x <- whatever_the_last_output_was

Thanks very much to the regexp wizards!
