plot.WGassociation: Function to plot -log p values from an object of class 'WGassociation'

Description

Function to plot -log p values from an object of class 'WGassociation'

Usage

# S3 method for WGassociation
plot(x, ...)

Value

No return value, just the plot

Arguments

x

an object of class 'WGassociation'

...

other graphical parameters

Details

A panel with different plots (one for each mode of inheritance) are plotted. Each of them represents the -log(p value) for each SNP. Two horizontal lines are also plotted. One one them indicates the nominal statistical significance level whereas the other one indicates the statistical significance level after Bonferroni correction.
