[R] Scoping problem

[halvorsen]

Hola!

I have the following simple function:

> testcar
function(pow){
           ob <- glm(Pound~CG+Age+Vage,data=car,weights=No,
                     subset=No>0,family=quasi(link=power(pow),var=mu^2))

           deviance(ob)
}
But trying to run it gives:

> testcar(1/2)
Error in power(pow) : Object "pow" not found

I have tried to use debug on testcar, but what I can find out is only
that pow
is invisible from within glm. Is there a way to find in which
environment
pow belongs, so as to get at it with "get" inside power?
