Not (yet) in R, but EPA's BMDS software (Windows only) will fit this model.

R-users,
Has anyone implemented (coded) the Rai and Van Ryzin dose-response model
from
their 1985 Biometrics paper. I'm trying to avoid re-inventing the wheel. If
not
any hints on coding this would be greatly appreciated.

Thanks,
--
