ppersp: Plot a 3-D profile of LODs

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

Description

Plot 3-D profile of LODs as function of genomic position and chemical shift

Usage

ppersp(z, ppm, title, theta=-15, phi=15, r=50)

Arguments

z	a matrix specifying metabolome genome-wide mQTL mapping results
ppm	a vector of chemical shift
title	plot title
theta	angle defining the viewing direction (azimuthal direction)
phi	angle defining the viewing direction (colatitude direction)
r	the distance of the eyepoint from the centre of the plotting box.

Value
