I have a small problem.  I am running glm() in R-0.61.0 on Redhat 4.2.
I want to get the standard errors from the output.  If I do

out <- glm(....)
summary(out)

I get the coefficients printed as well as their correlation matrix.  If I do 

out$coefficients  I get the coefficients
out$fitted        gives me the fitted values

I can then assign the fitted values or the value of the estimated coefficients
to a variable.  How do I get the covariance matrix of the estimates?

I have tried out$R but that gives me a matrix with numbers I don't understand.

Sorry to bug you with such a simple problem.
