circle_mQTL: Circular genome-metabolome plot for mQTL.NMR

In mQTL.NMR: Metabolomic Quantitative Trait Locus Mapping for 1H NMR data

Description

shows mQTL locations and relations with the metabolome on a central chemical axis

Usage

circle_mQTL(results, Th = 0, chr = 9, spacing = 25)

Arguments

results	a list containing mQTL mapping results generated by mQTL.NMR package
Th	a numerical parameter specifying LOD threshold
chr	a numerical value defining the chromosomes to show if necessary
spacing	a numerical parameter specifiying the sapcing between chromosomes on the circular genome

Value

A circuler plot where the central horizontal line corresponds to the NMR chemical axis, the circle represents the chromosomal positions, and the colored lines significant association between a shift and genomic location.
