draw.D14C: Draw d14C and the calibration curve.

In Maarten14C/IntCal: Radiocarbon Calibration Curves

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 = 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)
)

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).

Value

A plot of d14C and the calibration curve

Examples

  draw.D14C()
  draw.D14C(30e3, 55e3, ka=TRUE)
  draw.D14C(cc=ccurve("NH1_monthly"), BCAD=TRUE)
