Calculate highest posterior density ranges of calibrated distribution

The IntCal20 radiocarbon calibration curves (Reimer et al. 2020 <doi:10.1017/RDC.2020.68>) are provided here in a single data package, together with previous IntCal curves (IntCal13, IntCal09, IntCal04, IntCal98) and postbomb curves. Also provided are functions to copy the curves into memory, and to plot the curves and their underlying data, as well as functions to calibrate radiocarbon dates.

hpd function

<dl><dt>calib</dt>
<dd>The calibrated distribution, as returned from caldist()</dd>
<dt>prob</dt>
<dd>Probability range which should be calculated. Default <code>prob=0.95</code>.</dd>
<dt>return.raw</dt>
<dd>The raw data to calculate hpds can be returned, e.g. to draw polygons of the calibrated distributions. Defaults to <code>return.raw=FALSE</code>.</dd>
<dt>rounded</dt>
<dd>Rounding for reported probabilities. Defaults to 1 decimal.</dd></dl>
