Dear R super-users,

I am quite new in using R and I am not  managing to edit factors.

Lest suppose that one has the following data:

Factor A
 Factor B
 Factor C
Claims

Factor A has 3 factors (1,2 and 3). To simplify the glm model I only want to
have 2 factor (let's say 1 and 3).

I should I do this?

Thank you in advance.

Kind regards,
Pedro Sobral
