debug shows the problem is here. Examining that little section separately, it seems that update() and the for loop are not working together properly, but I am not certain how to fix it. > mod0 <- update(mod, .~1) > models <- c(mod0, models) class(models) <- "glmlist" > models > } > > -- Joshua Wiley Senior in Psychology University of California, Riverside http://www.joshuawiley.com/ [[alternative HTML version deleted]] ______________________________________________ R-help@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide http://www.R-project.org/posting-guide.html and provide commented, minimal, self-contained, reproducible code.
