[R] Order a matrix

Dear all, I just want to order a matrix using several columns in a matrix. For example: x <- matrix(sample(c(1:5), 60, replace = T), 10, 6). If I order the matrix by the first two columns, I will do it like this: x[order(x[, 1], x[, 2]), ]. But when I repeat this work many times and the colu

[R] order a matrix

Dear list, order(x,y,z) returns a permutation to order x, ties broken by y, remaining ties broken by z. (And so on.) What I'd like to do is order(X), where X is a matrix (or a list or data frame if necessary) of unspecified size, which orders X[,1], ties broken by X[,2], remaining ties broken
