Hi Simon, Thanks for your response. I am now running mgcv 1.7-13 on R-2.14. Having fixed this error, I now encounter the following when fitting this model
Error in qr.qty(qrx, yn) : 'qr' and 'y' must have the same number of rows Calls: bam -> bgam.fit -> qr.update -> qr.qty -> qr.qty bam(cbind(group0, temp)~1+ as.factor(AGEcat) + HSMF+BachMF+income.cpi+poverty+tobacco+tax+CigSalesPerCap+blacks+hisp+asian+native +s( year.centered , by= fips , bs='cr', k=8) +s( fips , bs='re'), gamma=1.6, family=binomial(link="logit"), data=data My sense is that the error is coming from the term s( year.centered , by= fips , bs='cr', k=8) as if I run the same model with s( year.centered, bs='cr', k=8) I don't get the error. Thus, something about trying to fit these smooths by fips id is causing the error. Do you have any ideas on what might be happening? I recognize it is hard to know without seeing the data....
