Power.t.test: Modified T-test Power Calculations

In nutterb/junkyard: Package development playground

Description

Allows for calculating power, effect size, or sample size over multiple conditions. Returns a data frame instead of an 'htest' object

Usage

Power.t.test(n = NULL, delta = NULL, sd = 1, sig.level = 0.05,
  power = NULL, type = "two.sample", alternative = "two.sided",
  strict = FALSE)

Arguments

n	Number of observations (per group)
delta	True difference in means
sd	Standard deviation
sig.level	Significance level (Type I error probability)
power	Power of test (1 minus Type II error probability)
type	Type of test
alternative	One or two-sided test
strict	Use strict interpretation in two sided case

Details

This is essentially a wrapper for a for loop over power.t.test.
