Description

Makes signal vs trait and formatted density plots from the data frame returned by CNVtest.qt

Usage

1
qt.plot(DataFrame.list, main='', hist.or.dens='histogram')

Arguments

DataFrame.list

The output obtained from the CNVtools fitting algorithm CNVtest.qt

main

Potential title for the graph

hist.or.dens

Either 'histogram' or 'density' to plot the data as an histogram or using a kernel density estimator
