MarginalPlot {ArchaeoPhases}

R Documentation

Plot a marginal posterior density

Description

Draws a plot of the estimated marginal posterior density for the one-parameter and adds the mean and the credible interval at the desired level

Usage

MarginalPlot(
  a_chain,
  level = 0.95,
  GridLength = 1024,
  title = "Characteristics of a date",
  subtitle = NULL,
  caption = "ArchaeoPhases",
  x.label = "Calendar year",
  y.label = NULL,
  y.grid = TRUE,
  x.scale = "calendar",
  elapsed.origin.position = NULL,
  x.min = NULL,
  x.max = NULL,
  height = 7,
  width = 7,
  units = "in",
  file = NULL,
  newWindow = TRUE
)

Arguments

a_chain	Numeric vector containing the output of the MCMC algorithm for the parameter.
level	Probability corresponding to the level of confidence.
GridLength	Length of the grid used to estimate the density.
title	Title of the graph.
subtitle	Subtitle of the graph.
caption	Caption of the graph.
x.label	Label of the x-axis.
y.label	Label of the y-axis.
y.grid	Switch for horizontal grid lines.
x.scale	One of "calendar" for calendar years, "BP" for years before present, or "elapsed" for time elapsed from a specified origin.
elapsed.origin.position	Position of the column to use as the origin for elapsed time calculations.
x.min	Minimum x axis value.
x.max	Maximum x axis value.
height	Plot height in units.
width	Plot width in units.
units	String recognized by the ggsave() function, one of "in", "cm", "mm".
file	Name of the file that will be saved if chosen, default = NULL.
newWindow	Whether or not the plot is drawn within a new window.

Details

The density is estimated using density() function with n = GridLength.

Value

NULL, called for its side effects
