SuccessionPlot {ArchaeoPhases}R Documentation

Density plots of two successive groups (for groups in temporal order constraint)

Description

Plot of the densities of the minimum and the maximum of the events included in each group, with summary statistics including the mean, credible interval, and highest posterior density. The result is given in calendar years (BC/AD).

Usage

SuccessionPlot(
  Phase1Min_chain,
  Phase1Max_chain,
  Phase2Min_chain,
  Phase2Max_chain,
  level = 0.95,
  title = "Characterisation of a succession of groups",
  exportFile = NULL,
  exportFormat = "PNG",
  GridLength = 1024
)

Arguments

Phase1Min_chain

Numeric vector containing the output of the MCMC algorithm for the minimum of the events included in the oldest phase.

Phase1Max_chain

Numeric vector containing the output of the MCMC algorithm for the maximum of the events included in the oldest phase.

Phase2Min_chain

Numeric vector containing the output of the MCMC algorithm for the minimum of the events included in the youngest phase.

Phase2Max_chain

Numeric vector containing the output of the MCMC algorithm for the maximum of the events included in the youngest phase.

level

Probability corresponding to the level of confidence.

title

Title of the plot.

exportFile

Name of the file to be saved. If NULL then no plot is saved.

exportFormat

Format of the export file, either "PNG" or "SVG".

GridLength

Length of the grid used to estimate the density.

Details

Curves represent the density of the minimum (oldest event) and the maximum (youngest event) of the events included in each group. Curves of the same color refer to the same group. Time range intervals are symbolised by segments above the curves drawn using the same color as curves of the associated group. Transition and gap range intervals are represented by two-coloured segments using the colors of the both groups in succession. If the gap between the successive groups does not exist, a cross is drawn instead of a segment.

Value

NULL, called for its side effects
