Computes the Sample Size of a Z-test for the Population Proportion

1	ssize.p.test(p0, p1, power = 0.9, sig.level = 0.05, alternative = "two.sided")

`p0`	The value of the population proportion from the null hypothesis (in decimal form)
`p1`	An alternative value of the population proportion
`power`	Power of the test
`sig.level`	Significance level, default is 0.05
`alternative`	type of alternative, with values "two.sided","less" or "greater"

Sample size required to achieve the given power

ssize.p.test(p0 = 0.10, p1 = 0.08, power = 0.9,
sig.level = 0.01, alternative = "two.sided")
ssize.p.test(p0 = 0.30, p1 = 0.25, power = 0.92,
sig.level = 0.10, alternative = "less")
