** 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.
