layer: Integer, numeric integer, or character: Layer from which to obtain category values.
db: Logical: If TRUE, return category numbers from the database table associated with the vector. If FALSE (default), return category numbers from the actual vector.
integer: Logical: If TRUE (default), return category values as integers. In some cases, a geometry can have multiple categories, in which case NA is returned. If FALSE, return category values as strings (and thus, if a geometry has more than one category, does not convert to NA).
