Dear R users,
I'm trying to use function 'refit' from lme4
and I get this error that I can't understand:
> refit(dolo4.model4,cbind(uu,50-uu))
Error in function (classes, fdef, mtable) :
unable to find an inherited method for function "refit", for signature
"mer", "matrix"
if I try:
> refit(dolo4.model4,uu)
Error in asMethod(object) : matrix is not symmetric [1,2]
I get this error message that I can no more
understand but which suggests that refit expects
two columns.
the initial model was:
> dolo4.mod...@call
glmer(formula = cbind(sortis, restes) ~ mean.co2 + (1 | sujet),
data = dollo4.df, family = binomial)
R version 2.9.0 (2009-04-17)
and
Package: lme4
Version: 0.999375-28
Date: 2008-12-13
thank you in advance
e.e.
