That won't work without some tweaking of the GLMM function. In the 0.95-1 and later versions of the lme4 package the capabilities of GLMM have been folded in to the lmer function and you would need to fit that model as lmer(OVEN ~ h + h2 + (1|yr), dataset, poisson) anyway. ______________________________________________ R-help@stat.math.ethz.ch mailing list https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide! http://www.R-project.org/posting-guide.html
