plot.compositeKDE {rcarbon}

Plots a Composite Kernel Density Estimate of sampled radiocarbon dates.

Description

Plots a Composite Kernel Density Estimate of sampled radiocarbon dates.

Usage

## S3 method for class 'compositeKDE'
plot(
  x,
  calendar = "BP",
  type = "envelope",
  ylim = NA,
  xlim = NA,
  fill.col = "lightgrey",
  interval = 0.95,
  line.col = "black",
  line.type = 2,
  multiline.alpha = NA,
  multiline.col = "black",
  ...
)

Arguments

x

A compositeKDE class object generated using the ckde function.

calendar

Either 'BP' or 'BCAD'. Indicate whether the calibrated date should be displayed in BP or BC/AD. Default is 'BP'.

type

Either envelope or multiline. Default is envelope.

ylim

the y limits of the plot.

xlim

the x limits of the plot. In BP or in BC/AD depending on the choice of the parameter calender. Notice that if BC/AD is selected BC ages should have a minus sign (e.g. c(-5000,200) for 5000 BC to 200 AD).

fill.col

Envelope color when type='envelope'. Default is 'lightgrey'.

interval

Quantile interval for the envelope. Default is 0.95.

line.col

Line color when type='envelope'. Default is 'black.

line.type

Line type when type='envelope'. Default is 2.

multiline.alpha

Alpha level for line transparency when type='multiline'. Default is 10/nsim, where nsim is the number of simulations. If nsim is smaller than 10, multiline.alpha will be set to 1.

multiline.col

Line color when type='multiline'. Default is 'black'.

Additional arguments affecting the plot

Details

Visualise a compositeKDE class object. If type is set 'envelope' an envelope of the percentile interval defined by the parameter interval is shown along with the mean KDE. If type is set 'multiline' all KDEs are shown.
