plot.BchronologyRun

Plot output from Bchronology

Description

Plots output from a run of Bchronology

Usage

## S3 method for class 'BchronologyRun'
plot(
  x,
  dateHeight = 100,
  dateLabels = TRUE,
  dateLabelSize = 2,
  dateCol = "darkslategray",
  chronCol = "deepskyblue4",
  chronTransparency = 0.75,
  alpha = 0.95,
  nudgeX = 0,
  nudgeY = 0,
  expandX = if (dateLabels) {     c(0.1, 0) } else {     c(0, 0) },
  expandY = c(0.05, 0),
  ageScale = c("bp", "bc", "b2k"),
  scaleReverse = TRUE,
  ...
)

Arguments

`x`	The object created by `Bchronology`
`dateHeight`	The height of the dates in the plot (on the same scale as the positions)
`dateLabels`	Whether to label the dates on the vertical axis (default TRUE)
`dateLabelSize`	The size of the date labels
`dateCol`	The colour of the date labels
`chronCol`	The colour of the chronology uncertainty ribbon to be plotted
`chronTransparency`	The amount of transparency for the chronology ribbon
`alpha`	The credible interval of the chronology run to be plotted. Defaults to 95 percent
`nudgeX`	The amount to move the date labels in the x direction. Can be negative. See `geom_text` for details
`nudgeY`	The amount to move the date labels in the y direction. Can be negative. See `geom_text` for details
`expandX`	The amount to expand the horizontal axis in case part are missed off the plot. See `expand_limits` for details
`expandY`	The amount to expand the vertical axis in case part are missed off the plot. See `expand_limits` for details
`ageScale`	Either `bp` for years before present, `bc` for years BC/AD (BC will be negative), `b2k` for years before 2000. Others not supported (yet).
`scaleReverse`	Whether to reverse the x-axis scale. Defaults to TRUE which works best for dates presented in e.g. years BP
`...`	Other arguments to plot (currently ignored)

Details

Creates a simple plot of the chronology output. The height of the date densities in the plots can be manipulated via the dateHeight argument which is represented in the same units as the positions/depths provided. More detailed plots can be created by manipulating the Bchronology object as required.
