Is this in a windows system? A TA of mine was just getting the exact
same message. He tracked it down to the pathname for Sweave.sty having
trouble with Program Files in the path.

Kevin,
Save yourself a lot of trouble and use my modified version of GNU
Emacs available from

I've been experimenting with R to compute simple statistics from my web

I'm trying to solve a homework problem using R. The problem gives a list
of cricket chirps per second and corresponding temperature, and asks to
give the equation for the linear model and then predict the temperature
to produce 18 chirps per second. So far, I have:

We just studied randomized block design analysis in my statistics class,
and I'm trying to learn how to do them in R. I'm trying to duplicate a
case study example from my textbook [1]:

dp - c(2, 1, 12, 11, 19)

I'm trying to replicate some of the examples from my textbook in R (my
