Dear all,
I recently started using Zelig in order to overcome some problems I had
with logistic modelling of rare events data in geomorphology (used SAS
before).
However I have memory problems with my computer when trying to analyse
the data in Zelig. Is this normal? I have about 16000 observations and
30 variables. This doesn't seem so much to me. However, even when I try
to run a demo, it gives a similar error message. (see copy of message
below)
I already changed the maximum memory allocated to R to 128Mb (=RAM of my
pc) as suggested in the FAQ that accompany R. Is there something else I
can try except buying a new pc?
Any suggestion would be welcome,
Tom

Hi,
Do you know the cause of this error in Zelig or R?
Error in "contrasts<-"(`*tmp*`, value = "contr.treatment")
What can I do to fix this error?
Thanks,
Sean
