Thanks a lot, Mark - the underscore fixed it immediately.

It doesn't like the dot in the function name. Use:
model = rpy.r.glm(formula, data = d, family = 'binomial', control =
rpy.r['glm.control'](maxit = 500))
or
model = rpy.r.glm(formula, data = d, family = 'binomial', control =
rpy.r.glm_control(maxit = 500))
