Hello. I am trying my hand at modifying the varFunc
class varExp, but I must be missing a step. All I
want to do right now is make a working copy of varExp,
call it varExp2, and then later change it.
coef.varExp2, coef-.varExp2, and Initialize.varExp2
all seem to work properly after I construct

Thanks Kevin and Roger. This gave me the clue and was a great help.
I have been trying it out. There is some problem in the code that still
needs to be figured out.
For the first 9 files, paste(wb-0, i, vc.dbf, sep=) works fine.
But as you rightly
Ah!! After way too many hours of work Ive answered my
own question. To get varExp2, a copy of varExp, to
work as a new varFunc, one needs to use this sort of
syntax:
update.varExp2 - function (object, data, ...)
{
print (enter update)
val - NextMethod()
if (length(val) == 0) {
I was hoping someone could help me!
How do you exclude outliers from a set of data?
Thanks,

Your question is too vague. I'm assuming you have a data frame and
already know exactly which observations are the outlier(s). If your data
frame is called foo.df, and say observation 5 is an

I don't understand why this is not working. Help is appreciated.
I need to plot the following as a surface, but persp returns an error.

Hi Steve,
persp() is looking for x and y to be the coordinates on the axes
rather than corresponding directly to the points. So, something like
x - c(1:3)
y - c(1:3)
z - c(1:9)
Take a look at the third example in help(persp) to clarify.
For your data you might try the surface() function in

Dear R people,
I have a naive question: after fitting lm to a data, I can't extract
the pvalue corresponding to a specific covariate in a direct way.
Could anyone give me a hint?
Thank you very much.

Hola!
I ask here since I learnt from this list that the LaTeX package listings
should be good
for typesetting R code. I encountered one problem:
\begin{lstlisting}
X %*% V
\end{lstlisting}
in the output the * in %*% disappears! same with %/%, etc, the /
disappears.
Any ideas?
