plot.PP: Job PP plot.

In BayesPeak: Bayesian Analysis of ChIP-seq Data

Description

Plot the PP profile of a particular job.

Usage

plot.PP(x, job, breaks = 150L, ...)

Arguments

x	Raw output from the bayespeak function.
job	Integer. Which of the jobs in the output should have its PP values plotted?
breaks	Integer. Analogous to the breaks argument in hist.
...	Additional arguments passed to the hist function.

Details

plot.PP plots a histogram of the PP values returned in a particular BayesPeak job. This can be used to identify overfitting in a particular job. It is not suitable for identifying the prevalence of overfitting in all of the jobs in a genome-wide analysis - for that, please see plot.overfitdiag.

Value

Plots a histogram on the active graphical device.
