changes in glm?

I am running some simulations which involve fitting a glm with 
Binomial error ( in fact Bernoulli) and logistic link. Running R 0.63 
I have no problems. However I need more speed so migrated to our UNIX 
boxes which run
Version 0.90.1  (December 15, 1999)

Here I get an error


Error in (if (is.empty.model(mt)) glm.fit.null else glm.fit)(x = X, y 
= Y,  : y must be univariate unless binomial


which has baffled me.
So I as your indulgence and ask

(1) What if anything has changed in glm from 0.63 to 0.90?
(2) Is glm sensative to changes of word length?
(3) Given making R on an Alpha is beyond me (so is a problem) should 
I migrate to a later version of R or does this bring more problems in 
its wake?
(4) Does anyone recognise the error and if so I would appreciate some 
info. I'm sure it is my stupidity but ..

Sorry to trouble you

The recent version is R-1.1.1 ! 
So it's a great idea to upgrade.

I shouldn't think anyone can remember -- that's a long time ago.

            

      
      
      
    

        
Shouldn't be.  I have used in on both 32-bit and 64-bit Solaris.

            

      
      
      
    

        
Yes, definitely update. Many many bugs were fixed before 1.0.0.  You won't
get any support for pre1.0 versions.  The newest version is 1.1.1, and
while a shiny new 1.2 is due out in a couple of weeks we expect quite a
lot of people to stick with 1.1.1 for the rest of the Northern hemisphere
academic year.

            

      
      
      
    

        
It's hard to tell without knowing exactly what you did to get the error.
The error means that glm() thinks you gave it a matrix rather than a
vector as the response (outcome, dependent) variable.

Remember, the purpose of a bug report is for us to reproduce the bug. This
isn't being difficult -- we usually can't fix bugs unless we can reproduce
them.

Bug reports get fixed a lot faster if they are of the form

	"I did X. Y happened. I think Z should have happened"

This involves central services, I believe, so it's not an immediately
fixable matter, but a request will be made.  I couldn't find the
changelog on the website in an obvious location -- did I just miss it?
