Additional arguments passed on to methods |
prior |
Character vector selecting the prior and posterior
distribution(s) to plot. May include |
post_args |
List of arguments passed on to ggplot2::geom_histogram to control plot output for the posterior distribution |
prior_args |
List of arguments passed on to ggplot2::geom_path to
control plot output for the prior distribution. Additionally, |
overlay |
String, should prior or posterior be shown on top? Default
|
ref_line |
Numeric vector of positions for reference lines, by default no reference lines are drawn |
Prior distributions are displayed as lines, posterior distributions are displayed as histograms.
A ggplot
object.
