I seem to come to this problem alot, and I can find my way out of it with a
loop, but I wish, and wonder if there is a better way. ?Here's an example
(lmer1-5 are a series of lmer objects):
?bs=data.frame(bic=BIC(lmer1,lmer2,lmer3,lmer4,lmer5)$BIC)
?rownames(bs)=c('lmer1','lmer2','lmer3','lmer4','lmer5')
?best=rownames(bs)[bs==min(bs)]
best
[1] "lmer5"
This tells me that lmer5 is the model with the lowest BIC. ?I want to start
working with lmer5 as the best model, such as fixef(best) to get the fixed
effect estimates from lmer5. ?I tried best=as.object('lmer5') but of course
this doesn't work because that is not a real function.
Does anybody see what I'm getting at? ?If so, do you know a way to do this
without a loop or series of if statements?
