Usage

sm_power(group1, group2, paired, sig.level = 0.05, power = 0.8)

Arguments

group2	Numeric vector containing data from another sample (i.e., group 2) that is to be compared with the former group.
paired	A logical indicating whether your two samples (group1 and group2) are paired.
sig.level	Significance level (Type I error probability). Default is set to 0.05.
power	Power of test (1 minus Type II error probability). Default is set to 0.8.

Value

Returns a result with a class of "power.htest" from the pwr package.

Examples

library(smplot2)
