Hello,
Could somebody please tell me what am I doing wrong in following?
I try extract coefficients (using arm-package) from the lmer
frunction, but I get the
following warning:
a<-data.frame(coef(res))
Error in as.data.frame.default(x[[i]], optional = TRUE,
stringsAsFactors = stringsAsFactors) :
cannot coerce class "coef.mer" into a data.fram
I think I have done it before the same way and it has worked, but not
any more..
Jukka
