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
to draw a graph
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 this in R.
Thanks
Suga
