[R] ordered probit or logit / recursive regression

[VUILLEUMIER Mathieu]

I make a study in health econometrics and have a categorical dependent variable (take value 1-5). I would like to fit an ordered probit or ordered logit but i didn't find a command or package who make that. Does anyone know if it's exists ?

other question : i would like to make a least square recursive regression. Is there a special command in R ?

Thanks for your answers.

Best regards,
