rintcal 0.5.1.1

the IntCal20 curves and their underpinning data are now available through a json file (code kindly contributed by Christopher Bronk Ramsey, University of Oxford)
calibrate now plots better when working in BC/AD

rintcal 0.5.0

added a function point.estimates to calculate the mode, median, weighted mean and midpoint of a calibrated distribution (after a suggestion by Alexandra Rouillard)
reading and writing of large files should now go faster if the data.table R package is installed (which doesn’t seem to work well on some Macs)
added functions F14C.D14C, D14C.F14C, age.F14C, F14C.age and contaminate
draw.ccurve now adds a legend if more than one calibration curve is plotted
draw.dates should behave a bit faster and draw more consistently sized distributions
added legacy ‘calibration’ data from Arnold & Libby 1951 (Science 113, 111-120)
Calibrated dates of postbomb dates are now drawn better

The C14.lim option to specify axis limits in the calibrate() function now works as expected
renamed the package from IntCal to rintcal, to highlight the fact that this package is not officially affiliated with the IntCal Working Group
added a function l.calib to calibrate multiple dates or calendar years
enhanced the options of the t model (Christen and Perez 2016) as alternative for the normal distribution

added an option ccdir to provide alternative locations of the calibration curves
added a function new.ccdir(), which copies the package’s calibration curves into a specified folder
C14.lim now works if 0 is included as minimum 14C age

updated to the updated postbomb curves (now both yearly and monthly), published by Hua et al. 2021
repaired problems with depths and calheights in draw.dates
draw.ccurve now plots correct label when BCAD
c14.lim now estimated correctly when a second curve is added

draw.ccurve now plots the correct label when using BCAD, and plots depths at the expected heights
draw.dates now plots multiple dates at the expected heights (with more precise dates peaking higher)
corrected the Rmd files which had erroneous formatting and some confusing examples

in mix.curves(), calibration curves are now written to a temporary directory by default, as per CRAN policies
calibrate function now deals better with postbomb dates
added clam’s function calBP.14C to find IntCal C14 ages corresponding to cal BP ages
added function glue.ccurves for gluing prebomb and postbomb calibration curves
added a warning/error to calibrate() for dates truncated by or outside the calibration curve
updated the vignettes

added new function list.curves
Shortened the functions copyCalibrationCurve and draw.CalibrationCurves to the shorter and more consistent ccurve and draw.ccurve
ccurve is now more flexible with the names of the calibration curves
draw.ccurve can now plot another curve on its own righthand axis scale (handy when mixing pre- and postbomb curves)
new functions calibrate, caldist and hpd, copied and modified from the clam R package

added a function intcal.data to plot the data underlying the IntCal curves
copyCalibrationCurve can now copy more of the curves
new function draw.calibration curve to draw the calibration curves (one or two), or to add curves to an existing plot)

Added Rd files
Added some of the most relevant calibrated-related functions of the rbacon package (so that these can in time be deleted from that and other packages)
