prop.multcomp function

Pairwise comparisons after a test for given proportions

Performs pairwise comparisons after a global test for given proportions, by using exact binomial tests.

prop.multcomp(x, p, p.method = "fdr")

Arguments

• x: contingency table.
• p: theoretical proportions.
• p.method: method for p-values correction. See help of p.adjust.

Returns

• method: name of the test.

• data.name: a character string giving the name(s) of the data.

• observed: observed proportions.

• expected: expected proportions.

• p.adjust.method: method for p-values correction.

• p.value2: corrected p-values.

• p.value: table or results of pairwise comparisons.
