BayesPeak (version 1.24.0)

plot.PP: Job PP plot.

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.

Value

Plots a histogram on the active graphical device.

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.
