concatenating two vectors

Dear all,
I want to concatenate the elements of two vectors such as
a<-c("a1","a2")
b<-c("b1","b2")
and obtain
"a1b1", "a1b2","a2b1","a2b2"
I tried the paste and paste0 functions, but they yielded elementwise
concatenation such as
"a1b1","a2b2"
I am wondering that is there an efficient way of doing my wish, for instance
without using for loop etc.
This is in the general frame of things which look like 'outer' (or Cartesian) products so you'll want to use the outer() function. I believe outer(a, b, FUN = paste0) should work. Cheers, Michael
