row*matrix
Hi all, I'm learning R. I'm used to Matlab and am having the following issue: I define a column vector and matrix and then multiply them. The result is not what I expect: v2 <- c(0,1,0) M <- cbind(c(1,4,7),c(2,5,8),c(3,6,9)) M*v2 [,1] [,2] [,3] [1,] 0 0 0 [2,] 4 5 6 [3,] 0 0 0 I expect the result to be a column, specifically the 2nd column of M.
