Dear R mailing listers,

I am try to find the different power calculation for
p1=0.2 and p2=0.4 , with significant level=0.05  (one sided test)
I would like to  have a graph   y -axis as a power and
x-axis as a sample size .

I run this command for different value of power. and get the n and power
pwr.2p.test(h=ES.h(0.4,0.2), power = 0.87,
sig.level=0.05,alternative="greater")

 Is there is any easy way i can do power graph using the two proportion in
R.



Thanks soo much any of  your help
