ihsplot(data,plot.pval="TRUE",ylim.scan=2,pch=16,main="iHS")

Arguments

data

A matrix with nsnps rows and 4 columns (Chromosome name, position of the SNP, iHS, Pvalue) (e.g. obtained using ihh2ihs function.

plot.pval

Either TRUE or FALSE if Pvalue should not be plotted

ylim.scan

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