It is easy to spot response nonlinearity in normal linear models using
plot(something.lm).
However plot(something.glm) produces artifactual peculiarities since the
diagnostic residuals are constrained by the fact that y can only take
values 0 or 1.
What do R users find most useful in checking the linearity assumption of
logistic regression (i.e. log-odds =a+bx)?
