Dear all,

I am encountering some odd results from the summary(object) command for
coxph and hurdle models. In both cases the result of summary(object)
function leaves out one of the categories of a categorical variable used in
the model. It is typically the first category if sorted alphabetically. Is
there any way around this problem?

For example, if I have categorical variable "type" with values {A,B,C,D,E},
it typically leaves out A in the result of the summary.

Thanks!
