[R] alternative to rep

[Bill Shipley]

Hello.  the rep(x) function replicates the vector x.  I am looking for a 
quick way of "expanding" a vector.  Here is what I mean by "expand":

given: x<-c(2,5,4)
If I "expand" x three times, then I will get 2,2,2,5,5,5,4,4,4.  In other 
words, I want to keep the original ordering (2,5,4) but duplicate each of 
the original entries three times.

Is there such a function?  If not, can someone suggest a fast way of doing 
this?

Thanks.
