\title{Create a quantile-quantile plot with ggplot2.}

|
\usage{
|
|
get_qqplot(ps, ci = 0.95, lambdaGC = FALSE, tol = 1e-08)

|
}

|
\arguments{
|
|
\item{ps}{Numeric vector of p-values.}
|
|
|
|
\item{ci}{Numeric. Size of the confidence interval, 0.95 by default.}
|
|
|
|
\item{lambdaGC}{Logical. Add the Genomic Control coefficient as subtitle to
|
|
the plot?}
|
|
|
|
\item{tol}{Numeric. Tolerance for optional Genomic Control coefficient.}

A ggplot2 plot.

\description{
|
|
Assumptions for this quantile quantile plot:
|
|
Expected P values are uniformly distributed.
|
|
Confidence intervals assume independence between tests.
|
|
We expect deviations past the confidence intervals if the tests are
|
|
not independent.
|
|
For example, in a genome-wide association study, the genotype at any
|
|
position is correlated to nearby positions. Tests of nearby genotypes
|
|
will result in similar test statistics.
