Greetings everyone;
I am not an R user; however, I am attempting to install R 2.7.0 on a
multi-user server for use by students and faculty in the Statistics
department here. I have an old version of R installed on the same
server, and it works fine; however, I am running into a problem
I am looking for a way to automatically detect outliers greater then X
standard devations then (here is the hard part) APPEND those dummy
variables to an existing array of regression variables (called cReg).
Any suggestions on how to go about this?
(source) sample data set that I am modelling:
Could someone please point me to where information about
the two entries %\VignetteDepends{} and %\VignettePackage{}
are documented?
I'm getting an error with %\VignetteDepends{} with my
package name in braces. Looking at the vignettes on my
system, some include the package name and some don't.

This definitely does the trick.
I knew there was an easier way!

I stumbled over a problem recently when trying to use srt with text() on a

What I intended to do was to plot a simple regression line, and to rotate

line.
However, the text is always plotted in a

A numerical value specifying (in degrees) how single characters

of 90 to work. Compare with srt which does string rotation.
So I would say that
