quartetTestPlot: Produce simplex plot with results of quartet hypothesis tests

Description

Plot a 2-d probability simplex, with points for all quartet count vectors. Colors indicate rejection or failure to reject for tests at specified levels.

Usage

quartetTestPlot(pTable, test, alpha = 0.05, beta = 1, cex = 1)

Arguments

pTable

table of quartets and p-values, as produced by quartetTreeTestInd, quartetStarTestInd, or NANUQ

test

model to use, for tree null hypothesis; options are "T1", "T3", "cut", "NANUQ"

alpha

level for tree test with null hypothesis given by test

beta

level for test with null hypothesis star tree; test results plotted only if beta<1 and "p_star" column present in pTable

cex

scaling factor for size of plotted symbols

Details

The first argument of this function is a table of quartets and p-values. The plot may show results of either the T1, T3, or 2-cut test, with or without a star tree test (depending on whether a "p_star" column is in the table and/or beta =1). The p-values must be computed by previous calls to quartetTreeTestInd (for "T1" or "T3" p-values) and quartetStarTestInd (for "star" p-values). The NANUQ and NANUQdist functions include calls to these tree test functions.
