chisq.multcomp function

Pairwise comparisons after a chi-squared goodness-of-fit test

Performs pairwise comparisons after a global chi-squared goodness-of-fit test.

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

Arguments

• x: numeric vector (counts).
• p.method: method for p-values correction. See help of p.adjust.

Details

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

Returns

• 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.
