I tried obj$p, obj$pvalue, but they both returned null~~

I have a cox.obj named obj,
obj <- coxph( Surv(time, status) ~ group, surv.data)
now I want to retrieve the p-value from obj, so that I can run this hundreds of times and plot out the distribution of the p-value. could anyone tell me how to get p-value from obj?

thanks,
