Hello all,

Using classical glm function with binomial family, I experienced a problem when using predict() over 
a glm object.
I found that family objects built on R-2.14.0 contain elements like :

But on R-2.9.0, the object C_logit_link can not be found. Instead, this prior version used to call 
more simply :

which causes no problem.

Is it possible to use R-2.14.0 family objects on prior R versions ?

I may have missed some note in R changes but tried some research at least.
Many thanks for help.

Kind regards,
