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
