plot.BchronCalibratedDates

Plot calibrated dates from a BchronCalibrate run

Description

Plots calibrated radiocarbon dates from a BchronCalibrate run. Has options to plot on a position (usually depth) scale if supplied with the original run

Usage

## S3 method for class 'BchronCalibratedDates'
plot(
  x,
  date = NULL,
  withPositions = ifelse(length(x) > 1 & !is.null(x[[1]]$positions) & !includeCal,
    TRUE, FALSE),
  includeCal = FALSE,
  dateHeight = 100,
  dateLabels = TRUE,
  dateLabelSize = 2,
  nudgeX = 0,
  nudgeY = 0,
  fillCol = "darkslategray",
  withHDR = TRUE,
  ageScale = c("bp", "bc", "b2k"),
  scaleReverse = TRUE,
  pathToCalCurves = system.file("data", package = "Bchron"),
  ...
)

Arguments

`x`	Output from `BchronCalibrate`
`date`	Either numbers or date names to plot (only used if multiple dates have been calibrated)
`withPositions`	Whether to plot with positions (i.e. using the position values as the y axis). By default TRUE if `x` has more than one date and contains positions
`includeCal`	Whether to plot the date alongside the calibration curve and the normally distributed uncalibrated date.
`dateHeight`	The height of the dates in the plot in the same units as the position values. Only relevant if `withPositions=TRUE`.
`dateLabels`	Whether to add the names of the dates to the left of them. Default TRUE
`dateLabelSize`	Size of the date labels
`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
`fillCol`	A colour to fill the date densities when `withPositions` is TRUE, or HDR ranges when it is FALSE
`withHDR`	Whether to plot the 95% highest density region values
`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
`pathToCalCurves`	The Bchron path to calibration curves. Defaults to the package location might need to be set to another folder if user defined calibration curves are being used
`...`	Other arguments to plot (currently ignored)
