WebAug 24, 2014 · In this way, you have simulated 1000 test statistics values under the null hypothesis. You actual test statistics is greater than all these 1000. That means that p-value at least is equal or lesser than 0.001 - that is ks.boot.p.value. Call ks.boot (red,black,nboots=10000) and you'll obtain ks.boot.p.value=0.0001.
