ihsplot: Plot iHS over a genome

Description

Plot iHS over a genome.

Usage

ylim.scan

An horizontal line is added at the corresponding coordinate, for instance to represent a significance threshold

pch

Type of the points representing SNPs in the plot(s)

cex

Size of the points representing SNPs in the plot(s)

cex.lab
