pairwise.G.test: Pairwise comparisons for proportions using G-tests

Description

Performs pairwise comparisons between pairs of proportions with correction for multiple testing.

Usage

pairwise.G.test(x, p.method = "fdr")

Arguments

x

matrix with 2 columns giving the counts of successes and failures, respectively.

p.method

method for p-values correction. See help of p.adjust.

Value

• method
  name of the test.
• data.name
  a character string giving the name(s) of the data.
• p.adjust.method
  method for p-values correction.
• p.value
  table of results.

Details

Since a G-test is an approximate test, an exact test is preferable when the number of individuals is small (200 is a reasonable minimum). See fisher.multcomp in that case.
