Hard to say:

 Can you give us a reproducible example, i.e. your data or a subset thereof
that
we can use to generate the same error message?

By the way,

glm(V1 ~ ., data=mytraindata, family=binomial)

should work equally well (you don't need to specify mytraindata$ before V1,
and the logit is the default link for the binomial family)
