Plot Quantile-Quantile Plot of p-values against uniform distribution.

Description

Plot Quantile-Quantile Plot of p-values against uniform distribution.

Usage

qqunif(
  x,
  outfn = NULL,
  conf.int = 0.95,
  plot.width = 5,
  plot.height = 5,
  thin = TRUE,
  thin.n = 500,
  zero.pval = "replace"
)

Arguments

x	a numeric vector of p-values. All values should be between 0 and 1.
outfn	a character. File name to save the QQ Plot. If outfn is supplied (i.e. !is.null(outfn)), then the plot is not drawn in the graphics window.
conf.int	a numeric between 0 and 1. Confidence band to draw around reference line. Set to NA to leave it out.
plot.width	a numeric. Plot width in inches.
plot.height	a numeric. Plot height in inches.
thin	a logical. Reduce number of data points when they are cluttered?
thin.n	an integer. Number of max points per horizontal partitions of the plot. Defaults to 500.
zero.pval	a character. Determine how to treat 0 pvals. "replace" will replace the p-value of zero with the non-zero minimum. "remove" will remove the p-value of zero.

Value

a ggplot object

Examples

x <- rbeta(1000, 1, 1)
qqunif(x)
