Dear All,
Does anyone know if there is any way to obtain the variance-covariance
matrix for any arbitrarily given estimates with the glm() function?
Here is what I really want. Given an arbitrary estimate (i.e., as starting
points with the start= argument), the glm() function could return the
What you are really asking is how environment variables get set outside of R,
which is very OS-specific and not on topic here, and there can be numerous ways
for it to happen even on a single OS. I will warn you that the path syntax can
vary in Windows depending on where it gets set so beware
Hi Dila,

transform(melt(dat,id.var=Day),Month=match(variable,month.abb),Year=2012,Amount=value)[,-c(2:3)]

models the robust variance has been rediscovered many times and so has lots of names: the

Ok. That's weird. If the stage= variables are indicators for levels of a

Could you show what coxph() gives? It has both the model-based and robust

I have been running successfully Westfall procedures to adjust p-values

However, the last model I tried consumes too much memory (40 Gb).

This will probably depend greatly on which operating system you are

I was curious if anyone developed a package/approach to installing

What I actually ended up doing is closing down RStudio and deleting the other

I understand that the robust variances may lead to a different

measurement variances (why I'm doing weighted fits in the first
place).

being general, and if I were making it into a function in a package,

Well, ?image and ?heatmap (! what else?) can do this -- except that
you probably want this on some sort of map projection, right? Assuming
that's the case, check the spatial task view on CRAN and/or post on
the r-sig-geo list . I am sure there are many packages that can do
various flavors of this.

Did you look at the help for agnes.object as directed by the help file

If none of those components meet your needs, as.hclust() - also

other methods that have the same asymptotic distribution as MLE. The

If all you want is the mean, why not do it in Java? That sounds like a half

Maybe one possiblity is to search complete cases, such as

It might also be interesting to check why you sometimes get NA.
