Sorry if this is a FAQ. Is there a good reason why a factor has to be a one-dimensional vector and cannot be a matrix?
I want to construct matrices of categorical values. Vain attempts like matrix(factor(c(T,F,F,T), 2,2) yield a matrix of character strings representing the factor levels, not the levels themselves, while factor(matrix(c(T,F,F,T), 2,2)) converts the matrix to a logical vector of length 4 then converts the vector to a factor.
