if NULL, will generate levels based on the unique values of x, ordered by order of appearance in x.. ordered: Is it an ordered factor? na: Character vector of strings to interpret as missing values. factor(x) applied to a factor is a no-operation unless there are unused levels: in that case, a factor with the reduced level set is returned. If exclude is used it should also be a factor with the same level set as x or a set of codes for the levels to be excluded.
