Discrete choice panel models in R

I know this question might have been around before like in this SO thread, but maybe (hopefully) its answer has changed over time.

• Is there any package in R or an outline how to do panel regressions with a discrete dependent variable?
• Is there any other open source package that does it and that would help coding something in R?
• the binary case might be a sufficient first start... – hans0l0 Apr 29 '11 at 9:48

What is wrong with using plm or lme4 (another link)? Particularly the glmer function?
• plm as far as I know does not have functions for fitting discrete data models. lme4 is a good suggestion, but should be used with care, since it assumes that all the independent variables are exogenous, which is not always the case for panel data in econometrics. – mpiktas May 30 '11 at 7:41
