You mean factor A has 3 *levels*, I think.
The question is how you want to remove level 2: exclude the observations
or join those in 2 with those of another level (hence making them
observations with level 1 or 3)?
BTW: A more worked out example would be helpful to provide example code
that solves your problem - as the posting guide suggests.
