Dear R-team
There seems to be a bug in glm.fit - I got the following error message:
> > > + Error in names<-.default(*tmp*, value = ynames) : names
attribute must be the same length as the vector
In addition: Warning messages:
1: fitted probabilities of 0 or 1 occurred in: (if (is.empty.model(mt))
glm.fit.null else glm.fit)(x = X, y = Y,
2: fitted probabilities of 0 or 1 occurred in: (if (is.empty.model(mt))
glm.fit.null else glm.fit)(x = X, y = Y,
3: fitted probabilities of 0 or 1 occurred in: (if (is.empty.model(mt))

Debugging glm.fit I found the following: when some elements of the vector
`good' are FALSE then `w' has no more "full" length:
w <- sqrt((weights * mu.eta.val^2)[good]/variance(mu)[good])
which leads to problems close to the end of the function:
names(w) <- ynames
as `ynames' has "full" length.
The same problem is with:
names(fit$effects) <- c(xxnames[seq(fit$rank)], rep("", nobs -
fit$rank))
as `fit$effects' has same length as `w'.
That's all I found out. I hope it helps.
I am sorry for not sending the data but as it is secret it would take some
effort to "disguise" it, so it that's not necessary I would be
quite
grateful...
Thanks, Peter
