Compare Empirical and t-distribution Approximated Calendar Age PDFs

Description

Compare the full empirical calendar age PDFs of calibrated radiocarbon dates with the t-distribution approximations use by hamstr

Usage

compare_14C_PDF(
  age.14C,
  age.14C.se,
  offset = 0,
  offset.se = 0,
  cal_curve = "intcal20",
  nu = 6,
  return.type = c("plot", "list"),
  dfs = rep(100, length(age.14C))
)

Arguments

age.14C	vector of radiocarbon dates in years BP
age.14C.se	vector of radiocarbon date uncertainties
offset	vector of offsets, e.g. reservoir ages.
offset.se	vector of offset uncertainties, e.g. sigmaDelatR.
cal_curve	calibration curve
nu	degrees of freedom of the t-distribution approximation, default in hamstr is 6
return.type	return a ggplot object or a list containing the ggplot object and two data frames with the empirical and t-distributions
dfs	Degrees-of-freedom values for the t-distribution associated with the calibration calculation. A large value indicates Gaussian distributions assumed for the 14C ages

Value

A ggplot2 object or list with data and ggplot2 object

Examples

compare_14C_PDF(age.14C = c(1000, 4000), age.14C.se = c(100, 150),
 cal_curve = "intcal20", return.type = "plot")
