Its hard to tell what did not work without a complete example but try replacing lm with dyn$lm. Using built in Nile: library(dyn) fit.model <- dyn$lm(Nile ~ time(Nile)) plot(Nile) lines(predict(fit.model)) -- Statistics & Software Consulting GKX Group, GKX Associates Inc. tel: 1-877-GKX-GROUP email: ggrothendieck at gmail.com ______________________________________________ [email protected] 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.
