plotMostDiscordant {consensus} | R Documentation

## Plot a heatmap showing a selection of loci

### Description

Plots a heatmap of a specified number of loci showing per-platform, values for either (a) average (a_i), (b) sensitivity (b_i) or (c) precision (d_i) for the most discordant for each. Discordance is ranked by V(a_i), V(b_i) or \frac{Σ(d_i)}{p-1} where p= the number of platforms/conditions.

### Usage

    plotMostDiscordant(consfit, param=c("average", "sensitivity", "precision"),
                       numloci=20, pal=colorRampPalette(brewer.pal(9, "RdYlGn")))

### Arguments

`consfit` | An object of class `ConsensusFit`.
`param` | Whether average (a_i), sensitivity (b_i) or precision (d_i) is plotted.
`numloci` | The number of loci to plot.
`pal` | Colour palette. Length must be at least the number of platforms/conditions.

### Value

A plot to the current device.
