Thanks Hadley!
While I got your attention, what is a good way to get started on ggplot2? ;)
My impression is that I first need to learn plyr, dplyr, AND THEN ggplot2.
That's A LOT!
Suppose i have this:

iris2 <- cbind(iris, grade = sample(1:5, 150, replace = TRUE))

Yes.
To elaborate a bit on Ista's reply:
A) The only way I can imagine hiding info from a user would be to encrypt
it. This could be done programmatically I think, but I would have to
research it to figure out how.
B) If all you want to do is prevent the info from being printed, just
create e.
It depends on what you mean by 1). If you mean "won't annoy the user" then
yes, e.g., add something to the class attribute. If 1) means "can't be
discovered by the user" then no (at least not easily). Anything you can see
they can see.

Not by the mail server as such, no, at least not for that reason. However,
T-bird likely sends .txt as text/plain and .R as application/octet-stream (or
so) and _therefore_ the server eliminates the latter and lets the former pass.

The quantile function is just the inverse of the distribution function, so
if you have the latter you can always get the former, e.g by simple
interpolation using approx(). Assuming you can't find it already written
for you of course.

Is there a function in R that can calculate the quantiles or percentiles
