[R] glm predict on new data

I am aware this has been asked before but I could not find a resolution.
I am doing a logit
lg <- glm(y[1:200] ~ x[1:200,1],family=binomial)
Then I want to predict a new set
pred <- predict(lg,x[201:250,1],type="response")
But I get varying error messages or warnings about the different number of
rows. I have tried data/newdata and also to wrap in data.frame() but cannot
get to work.
Help would be appreciated.
