R help - Sep 2011 - onet.permutation()

I saw the manual of this function but not sure what to do. 
I have a array contain 7 numbers and want to choose 4 to do permutation
test. But using this function with parameters as onet.permutation(scores,4),
it returns 0. Instead, with no parameter, onet.permutation(), it returns
something but every time it's different.
Please tell me how am I supposed to do it.
Thanks a lot

** I am not a statistician, but...
 
The default arguments are:
onet.permutation(x, nsim=2000, plotit=TRUE)

you are making nsim=4   (this parameter is not the size of each sample, it
is the number of samples taken)
You are building the distribution for a statistical test through random
sampling, so you want to have MANY MANY random samples, not just 4.
