Why does R need the concept of "Vector"? In my opinion, it is a useless and confusing concept. A vector is simply a special case of a matrix whose row or column number is equal to 1. When I take submatrix from one matrix and if row or column number is 1, R will automatically convert it into a vector. It is very straightforward that a submatrix of a matrix should be a matrix. In each time, I have to use as.matrix() to convert the vector back to matrix. It is very annoying! -- View this message in context: http://n4.nabble.com/Confusing-concept-of-vector-and-matrix-in-R-tp1707170p1707170.html Sent from the R help mailing list archive at Nabble.com.
