Hi,
I used subset command, like this:
grupoP = subset(dados, grupos=='P', select=c(mortos, vivos,
doses, percevejos, p))
and the variables in select option are numeric.
I tried fit a model with command:
ajuste.logit = glm(cbind(mortos,percevejos)~log10(doses),
family=binomial(logit), data=grupoP)
and the output is:
ajuste.logit = glm(cbind(mortos,percevejos)~log10(doses),
family=binomial(logit), data=grupoP)
Erro em Math.factor(doses) : log10 not meaningful for
factors
what is wrong with my commands? Why doses aren't numeric?
Thanks,
