See the function definition, it is very simple. _V_a_l_u_e: A numeric or complex array of suitable size, or a vector if the result is one-dimensional. The `dimnames' (or `names' for a vector result) are taken from the original array. _A_u_t_h_o_r(_s): Wolfgang Huber _S_e_e _A_l_s_o: 'rowMeans' and 'rowSums' _E_x_a_m_p_l_e_s: a = matrix(rnorm(1e4), nrow=10) rowSds(a)
