draw.D14C: Draw d14C and the calibration curve.

Description

Draw a proxy of the atmospheric 14C concentration (d14C) as well as the calibration curve.

Usage

draw.D14C(
  cal1 = c(),
  cal2 = c(),
  cc = rintcal::ccurve(),
  BCAD = FALSE,
  mar = c(4, 4, 1, 4),
  mgp = c(2.5, 1, 0),
  xaxs = "r",
  yaxs = "r",
  bty = "u",
  ka = FALSE,
  cal.lab = c(),
  cal.rev = FALSE,
  C14.lab = c(),
  C14.lim = c(),
  cc.col = rgb(0, 0.5, 0, 0.5),
  cc.border = rgb(0, 0.5, 0, 0.5),
  D14C.lab = c(),
  D14C.lim = c(),
  D14C.col = rgb(0, 0, 1, 0.5),
  D14C.border = rgb(0, 0, 1, 0.5)
)

Value

A plot of d14C and the calibration curve

Arguments

cal1: First calendar year for the plot. Defaults to youngest calendar age of the calibration curve
cal2: Last calendar year for the plot. Defaults to oldest calendar age of the calibration curve
cc: The calibration curve to use. Defaults to IntCal20
BCAD: The calendar scale of graphs and age output-files is in cal BP (calendar or calibrated years before the present, where the present is AD 1950) by default, but can be changed to BC/AD using BCAD=TRUE.
mar: Plot margins (amount of white space along edges of axes 1-4).
mgp: Axis text margins (where should titles, labels and tick marks be plotted).
xaxs: Whether or not to extend the limits of the horizontal axis. Defaults to xaxs="r" which extends it by R's default.
yaxs: Whether or not to extend the limits of the vertical axis. Defaults to yaxs="r" which extends it by R's default.
bty: Draw a box around the graph ("n" for none, and "l", "7", "c", "u", "]" or "o" for correspondingly shaped boxes).
ka: Use kcal BP (and C14 kBP). Defaults to FALSE.
cal.lab: The labels for the calendar axis (default age.lab="cal BP" or "BC/AD" if BCAD=TRUE), or to age.lab="kcal BP" etc. if ka=TRUE.
cal.rev: Reverse the calendar axis (defaults to FALSE).
C14.lab: Label for the C-14 axis. Defaults to 14C BP (or 14C kBP if ka=TRUE).
C14.lim: Limits for the C-14 axis. Calculated automatically by default.
cc.col: Colour of the calibration curve (fill).
cc.border: Colour of the calibration curve (border).
D14C.lab: Label for the D14C axis.
D14C.lim: Axis limits for the D14C axis. Calculated automatically by default.
D14C.col: Colour of the D14C curve (fill).
D14C.border: Colour of the D14C curve (border).
