qq: Creates a Q-Q plot

In fastqq: Faster Generation of Quantile Quantile Plots with Large Samples

Creates a Q-Q plot

Description

Creates a quantile-quantile plot from p-values from an association study, e.g. a genome wide association study (GWAS). We compare the data quantile with a theoretical quantile from a uniform distribution. This code is mostly adapted from the qqman package, but improved for speed. A graph with a hundred million points should only take a few seconds to generate.

Usage

qq(pvector, ...)

Arguments

pvector	A numeric vector of p-values.
...	Other arguments passed to plot()

Value

No return value, called for plotting side effects.

Examples

qq(stats::runif(1e6))
