Use print() on a family object

USAGE:

print.family(x, ...) 

This is a method for the function print() for objects inheriting from class family. See print or print.default for the general behavior of this function.
A family object is a list of functions and expressions. All that is printed is an identification label. To see the functions themselves, access the individual components, or use print.default() or unclass()

EXAMPLES:

binomial(link=probit) 
binomial(link=probit)$deriv
