Dear R helpers Suppose
x <- c(1:3) y <- matrix(1:12, ncol = 3, nrow = 4) > y [,1] [,2] [,3] [1,] 1 5 9 [2,] 2 6 10 [3,] 3 7 11 [4,] 4 8 12 I wish to multiply 1st column of y by first element of x i.e. 1, 2nd column of y by 2nd element of x i.e. 2 an so on. Thus the resultant matrix should be like > z [,1] [,2] [,3] [1,] 1 10 27 [2,] 2 12 30 [3,] 3 14 33 [4,] 4 16 36 When I tried simple multiplication like x*y, y is getting multiplied column-wise > x*z [,1] [,2] [,3] [1,] 1 5 9 [2,] 4 12 20 [3,] 9 21 33 [4,] 16 32 48 Kindly guide Regards Vincy [[alternative HTML version deleted]]
