[R] Vector multiplication

[Kaspar Bernet]

Hi, 

this may sound stupid (and it probably is), but I can't seem to find out how to multiply each element of a vector with each element of another vector where the result would be a matrix of dim[length(vectorOne),length(vectorTwo)] without using loops. 

example: if

a -> c(1,2,3)
b -> c(4,5,6)

i'm looking for the operation that would yield:

    [,1] [,2] [,3]
[1,]    4    8   12
[2,]    5   10   15
[3,]    6   12   18

any hints are greatly appreciated, 
kaspar
