[R] Cumulative distribution estimation

[Murray Jorgensen]

Apologies for bothering the list for something that I could probably have
worked out myself had I brought my V&R in to work!

I have been asked how to construct useable cdf's and quantile functions
from density() output. If I were using Minitab I'd begin by making partial
sums of the density values and normalizing to a maximum of 1, but I don't
know the R analogue to the Minitab PARSUMS command.

Any suggestions?
