[R] Intersection for two curves

[Peter Ehlers]

Well, this has seriously gotten off the original topic.

While Hadley makes some sense, it is nevertheless
sometimes the case (surely so for David, I would surmise)
that one is putting together a response to an R-help
query when a new query prompts one to temporarily abandon
the first and formulate a response to the second. One
may well prefer not to have one's workspace cleared even
though this would not lose more than the temporarily
suspended work. So, is ther *ever* a good reason to
*not* put rm(list=ls()) behind a comment char? I doubt it.

Just my 2c.
