Many hypothesis tests for two means of percentages

Description

Many hypothesis tests for two means of percentages.

Usage

percent.ttests(x, y, logged = FALSE)

Arguments

x	A numericalmatrix with the percentages of the first sample. Any value between 0 and 1 (inclusive) is allowed.
y	A numerical matrix with the percentages of the first sample. Any value between 0 and 1 (inclusive) is allowed.
logged	Should the p-values be returned (FALSE) or their logarithm (TRUE)?

Details

This is the prop.reg but with a single categorical predictor which has two levels only. It is like a t-test for the means of two samples haivng percentages.
