[R] Survivors and bugs ...

[John Logsdon]

Two questions:

I have a lot of data for which the last of each of the repeated individual
obserations is censored.  Apart from the suite in survival, which seems to
be very complex to a new R user, is there any other simple function that
exists in CRAN library (I have most of these but haven't found one!) that
is essentially the same as lm() but with an additional censor argument
(vector of -1,0,1 say, recalling my GLIM background) so that the left,
uncensored or right censored data may be simply analysed. 

Obviously I could write my own fairly simply using nlm() and model frames
but just asking ... if I write my own, I can post it on the list. 

The second question relates to a few problems with glm() that have been
found today and recently (the offset problem) by Jim comparing with his
own glmm() function. I don't follow the r-bugs list (these things are too
depressing!) but are these bugs either serious, occasional or a result of
esoteric problems?  One would like to know since I don't have immediate
access to (say) S+ to see whether the results are the same (or the errors
reproduced).
