rintcal 1.0.0

• most functions have been transferred into the new R package rice. The rintcal package will become a data package with only very few functions remaining (related to loading/combining curves, and plotting/querying the intcal data)
• in mix.ccurves, errors are now calculated correctly
• intcal.data can now also plot the C14 data in the ‘realms’ of F14C, pMC and D14C

rintcal 0.6.4

• mix.ccurves now doesn’t fail if a provided cc.dir folder does not yet exist
• mix.ccurves now saves the calibration curves with values separated by a single space, not by a tab
• as per Kurt Hornik’s e-mail, added a sentinal “_PACKAGE” to the documentation
• as per Prof. Brian Ripley’s e-mail, removed permille sign of draw.D14C function as graphics devices such as of OSX do not always draw them
• some minor changes to how postbomb dates are treated and plotted

rintcal 0.6.3

• further enhancements to functions ccurves, calibrate and caldist, especially for young dates close to the prebomb limits
• updated vignette

rintcal 0.6.2

• a bug in ccurves causing problems with plotting and cc=4 has been corrected

rintcal 0.6.1

• calibration of dates close to 0 14C BP now uses both prebomb and postbomb curves by default (if postbomb is provided)

rintcal 0.6.0

• the files containing the NH and SH postbomb curves are now printed with the youngest cal BP years at the top
• 0 BC/AD (which does not exist) is now dealt with better
• added a function draw.contamination
• the calibrate function now deals better with BC/AD (e.g., new items can be added afterward in the expected locations)
• mix.ccurves now handles varying offsets (mean and/or uncertainty)
• intcal.data now has more colours, returns datasets (invisibly) and can plot selected datasets

rintcal 0.5.3

• added a function draw.D14C to draw the D14C data together with the calibration curve.
• added an option draw.base to draw.dates

rintcal 0.5.2

• 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

rintcal 0.4.2

• made draw.dates more flexible, e.g. can now rotate axes

rintcal 0.4.1

• updated the documentation to include value entries for each function
• ensured that no data is written into userspace by default, as per CRAN policies
• enhanced functions to set par values more gracefully

rintcal 0.4.0

• 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

IntCal 0.3.1

• 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

IntCal 0.3.0

• 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

IntCal 0.2.3

• 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

IntCal 0.2.2

• 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

IntCal 0.2.1

• 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

IntCal 0.2.0

• 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)

IntCal 0.1.3

• fixed issues with the DESCRIPTION file

IntCal 0.1.2

• 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)

IntCal 0.1.1

• fixed some errors in the description file

IntCal 0.1.0

• first iteration of this R data package (originally put on github)
