Hello Sara,
you can read the p-value from the following that you obtain in the listing:
number of random permutations: 5000 Observed: 1.123e+00
Histogram: minimum = 6.455e-01, maximum = 1.196e+00
number of simulations X<Obs: 4993 (frequency: 9.986e-01)
number of simulations X>=Obs: 7 (frequency: 1.400e-03)
You test the projected inertia (i.e. the quantity of Y (.xxta) that you can
explain by X (.@ob)).
The "number of simulations X>=Obs" give you the number of permutations
providing a better explanation that your real data. the p-value is this
number divided by the number of permutation (here, frequency: 1.400e-03)
=> very significant.If this number is equal to 0, then you can say that the
p-value is inferior to 1/(number of permutation).
