I have
mat<-matrix(1:12,3) vect<-c(2,2,2)
How can I multiply each column by the vector in order to obtain:
2, 8, 14, 20 4, 10, 16, 22 6, 12, 18, 24
vect*mat [,1] [,2] [,3] [,4] [1,] 2 8 14 20 [2,] 4 10 16 22 [3,] 6 12 18 24
The vector vect is recycled by column. Better to experiment with different values to see the process.
