Kinship2 and GenABEL

Hi,

I'm using kinship2 to calculate heritabilty, but I would like calculate in
GenABEL too.

I trying the code:

require(kinship2)
require(GenABEL)

pedig = with(Dados, pedigree(id=IID, dadid=PAT, momid=MAT, sex=SEX,

famid=FID, missid=0))

kmat = kinship(pedig)

(mod1 = polygenic(altura ~ SEX + idade, data=Dados, kin=kmat))

Erro em intI(i, n = d[1], dn[[1]], give.dn = FALSE) :
  invalid character indexing

How can I calculate heritabilty using GenABEL with kinship matrix of
kinship2 package?

Thanks,
