"I have problems" isn't enough for us to diagnose. I tried this trivial example in base R: > d <- data.frame(x=runif(4e5),y=rpois(4e5,5)) > system.time(glm(y~x,family=poisson,data=d,trace=TRUE)) Deviance = 438614.6 Iterations - 1 Deviance = 417968.2 Iterations - 2 Deviance = 417921.2 Iterations - 3 Deviance = 417921.2 Iterations - 4 user system elapsed 5.444 12.952 18.429 Can you give us a hint about what went wrong?? ______________________________________________ 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.
