RJava: getting mean() of Integers[]

how can i get the mean of some Integers[]?

i have R-1.2.3 and RJava installed (and working).  i
was wondering how to pass "vectors" as arguments to R
from Java?  an example may be the mean() function, as
it takes a vector of integers.

I can do:  mean(c(1,2,3,4))
I can _not_ do: mean(1,2,3,4)

How about something based on:

mymean <- function(...){mean(c(...))}
mymean(1,2,3,4)

[1] 2.5

Hope this helps,
