[R-sig-ME] Error in initializePtr() : updateMu: Size mismatch

[Pamela Ochungo]

Hallo,

I want to run a linear mixed model featuring 5 response variables and only
one predictor variable. I also have two random effects in the model. I am
using this code:

lm1 <- lmer(cbind(transpopbees, transbrood, transhoney, transpollen,
transeggs) ~ Varroa+(1|Site)+(1|Colony),data=pollencolony)

However I get this error message:

Error in initializePtr() : updateMu: Size mismatch

What does this mean and what am I doing wrong?

Thanks
