I've encountered a problem using expand.model.frame() with a model specified

mod - lm(y ~ x)

Dear Gabor,
That solves the problem -- thank you very much for the quick response.
(I did look at the source for expand.model.frame but didn't isolate the
problem, which seems clear now that you've pointed it out.)
Regards,

hello,
i have just started exploring R as an alternative to matlab for data analysis.
so far everything is _very_ promising. i have a question though regarding
parameter estimation. i have some data which, from a histogram plot, appears to
arise from a gamma distribution. i gather that you can

If you do a lot of exports from R to excel, you might want to use
a wrapper function around write.table(). I got tired of using
write.table(), go to excel, select file and load routine.
My solution to the problem is to create a simple function that
opens excel spreadsheet automatically from R.
Is it possible to make multiple plots i.e. to represent more than one
function on the same figure?
Thank you

Hi R users!
I will try to state my question again. I have longitudinal data and fitted the
following model with lme:
Y = X*beta + U + W(t) + Z
where
U ~ N(0, nu*I) I is the identity matrix, so this is the random intercept
W(t)~ N(0, sigma*H) and H is a matrix which incorporates a

It you want to superimpose the curves, for example:
t=seq(-5,5,.1)
plot(t,exp(-t*t),type='l')
lines(t,sin(t)*sin(t))
If you want to plot on separate plotting

The version of ?install.packages (in R-2.0.1) I've read never said it could
install local source packages, so why would it be considered a bug not being
able to do something that is never claimed? You seem to expect the function
to do something that it is never designed to do.

By the way, do you get this error in a recent version of R (say = 1.9.1). I
