There's one very important similarity between these calls: you probably
shouldn't use either of them. Calling methods directly is generally a bad
idea.

residuals.lm() returns the $residuals component of the object. In an lm()
this is the residuals, but in a glm()  it is the working residuals. That's
why you shouldn't call residuals.lm() on a glm.

residuals.glm(, type="response") returns the observed value minus the
fitted value.
