plot.vhica: Plots a VHICA regression between two species.

In vhica: Vertical and Horizontal Inheritance Consistence Analysis

Plots a VHICA regression between two species.

Description

The VHICA method is based on a contrast between gene divergence and codon usage bias. A regression between divergence and codon usage provides a reference, and sequences of interest (typically, transposable elements) will be compared to the reference genes.

Usage

## S3 method for class 'vhica'
plot(x, sp1 = NULL, sp2 = NULL, ...)

Arguments

x	An object of class vhica, created by read.vhica.
sp1	Name of the first species, as in the data files.
sp2	Name of the second species, as in the data files.
...	Additional options for plot.

Details

The resulting figure displays genes as circles, and transposable elements as symbols.
