In SNPassoc: SNPs-Based Whole Genome Association Studies

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 class 'WGassociation'
plot(x, ...)

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.

Value

No return value, just the plot
