ccurve: Copy a calibration curve

In IntCal: Radiocarbon Calibration Curves

Copy a calibration curve

Description

Copy one of the calibration curves into memory.

Usage

ccurve(cc = 1, postbomb = FALSE, ccdir = NULL)

Arguments

cc	Calibration curve for 14C dates: cc=1 for IntCal20 (northern hemisphere terrestrial), cc=2 for Marine20 (marine), cc=3 for SHCal20 (southern hemisphere terrestrial). Alternatively, one can also write, e.g., "IntCal20", "Marine13".
postbomb	Use postbomb=TRUE to get a postbomb calibration curve (default postbomb=FALSE). For monthly data, type e.g. ccurve("sh1-2_monthly")
ccdir	Directory of the calibration curves. Defaults to where the package's files are stored (system.file), but can be set to, e.g., ccdir="curves".

Details

Copy the radiocarbon calibration curve defined by cc into memory.

Value

The calibration curve (invisible).
