Hello I am trying to compare two models using anova(), however I get a message error (see below). In the net I only found some information on certain library(car) for which one should use anova with A capital letter (Anova instead of anova), but I could not find car library as it says it does not exist.
> Model <- lm(interceptG ~ SW + TSC + FSC + PF + SlopeG + K, data=AllTrait) > Model1 <- lm(interceptG ~ SW + TSC + FSC + PF + SlopeG + PHt, data=AllTrait) Error in anova.lmlist(object, ...) : models were not all fitted to the same size of dataset I have NA in the datafile, should that be the problem? Kind regards and thanks in advance Rosario ______________________________________________ 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.
