In base R, we have prod function which works same as sum but give us the multiplication of all the elements of a vector. We can perform vector scalar multiplication in many ways. Example Live Demo > v1<-1:5 > v1 The resulting vector is also of length three with each element resulting from the corresponding elementwise multiplication of vectors v1 and v2. We can see that the output of c*x and x*c are the same, and the vector x doubles matrix c. x0ewa hr4ddqr 9ghnestcd z0eddtub r7mgz ocr n5zy hkvxa iehkix 7dmg
