[R] Running a likelihood ratio test for a logit model

Hi all --

   I have to calculate a likelihood ratio test for a logit model. I found logLik, but I need to calculate the log likelihood for the model without any predictors. How can I specify this in glm? If the full model is glm(y ~ x1), is the one without predictors (y ~ 0)? Or (y ~ 1)?

   Is there a more direct way of getting this?
