Obtaining R-squared value in Logistic Regression

I do not see an R-squared value after preforming the glm regression.

Is there a separate command for this?

A logistic regression is fitted via maximum likelihood, not by least 
squares.
Unless I am very much mistaken (always a contingency to be considered!)
R-squared makes no sense at all in this context.

Read up on "deviance".
