[R] Calculation of Covariance Matrix Calculation

Hi, Excuse me for asking this silly question. But I really couldn't understand why cov() and ccov() don't work for my calculation of covariance matrix. a <- matrix(1:8, 2, 4) a [,1] [,2] [,3] [,4] [1,]1357 [2,]2468 > ccov(a) Error in solve.default(cov, ...) :
