Isn't it the case, that since R 2.40 that all one ought to need do is
define one's own link and pass it to the family, rather re-defining the whole
family?
CHANGES IN R VERSION 2.4.0
...
o make.link() now returns an object of class "link-glm".
The GLM families accept an object of this class for their
'link' argument, which allows user-specified link functions.
Also, quasi() allows user-specified variance functions.
I thought that was the point of the example on the family help page.

Douglas Bates a écrit :
Look at the 'link' component of the two lists. In the binomial family
object the link component is a character vector of link 1. In your
logexposure family object it is a list of length 5.
