Bchron 4.7.8

• Changed the arguments to summary.Bchronologyrun to allow for moreflexibility in the accumulation rate estimation
• added a test (test_order.R) for when the order of the data set ischanged
• Fixed a bug in the way Bchronology was returning the radiocarbondates when they weren’t given in depth order

Bchron 4.7.7

• Added an example for reservoir correction in the vignette
• Corrected new email address at UCD
• Fixed bugs on the check page.

Bchron 4.7.6

• Fixed an example in Bchronology that was adding titles/labelsincorrectly
• Updated vignette to show how to customise plots
• Fixed a bug where an error for identical positions (with nothickness errors) was not being shown
• Fixed an issue with positionNormalise
• Fixed an issue with jitterPositions by replacing it withartificialThickness that enables customised amounts of jittering whenthere are identical positions and no thicknesses
• Forced ids argument in BchronCalibrate and Bchronology to be uniqueotherwise causes problems with plots

Bchron 4.7.5

• Added in a BchronCheck function to allow for checking of allargument types using checkmate
• Added in positionEps argument to Bchronology to avoid positionsbeing simulated too close to each other and leading to numericalunderflow errors
• Changed default colours of dates in plot.CalibratedDates andplot.BchronologyRun
• Added an extra check that all ageSds are bigger than zero
• Allowed the option for calibrating dates out of calibration curverange
• Fixed bug that occurred with large 14C values close to upper rangeof calibration curve
• Changed the means by which starting values are created. This was tofix a bug (issue #17 on GitHub) where a middle extreme date(e.g. non-14C) could cause the starting values of the stratigraphicallyordered dates to fall beyond the range of the calibration curve.
• Included option to allow bespoke starting values for complexcores
• Changed some of the algorithm details to avoid certain bugs withnumerical underflow problems (tested in test_all_chrons)

Bchron 4.7.4

• Updated the BchronDensity and BchronDensityFast functions to showlines on top of dates
• Included ability in above functions to change amount of datetransparency
• Used styler to make the syntax follow tidyverse styleguidelines
• Fixed bug in starting values which occasionally produced valuesbefore the extractDate
• Fixed bug in choosePositions where position chosen was at the edgeof the domain

Bchron 4.7.3

• Fixed a weird bug where some hdrs were coming out the wrong way inplot.Bchronology
• Add the ability to create OxCal style plots with the calibrationcurve
• Added a feature to plot individual dates inplot.BchronCalibratedDates

Bchron 4.7.2

• Included intcal20, shcal20, and marine20 new calibration curves

Bchron 4.7.1

• Fixed a bug in Bchronology that caused incorrect predictions

Bchron 4.7.0

• Fixed a(nother) small bug in predict.Bchronologies
• Included proper testthat, travis, and code coverage

Bchron 4.6.1

• Fixed bug in predict.Bchronologies

Bchron 4.6

Fixed two important bugs:

• Fixed a mistake in BchronCalibrate that will cause calibrated tohave incorrect error ranges compared to OxCal
• Fixed a problem that occurred in very straight chronologies where acertain parameter would go to zero and cause numerical underflow

Bchron 4.5

• Fixed some minor issues with ggplots
• Added in code for scaling the x-axis

Bchron 4.4

• Changed plots to use ggplot2 via ggridges

Bchron 4.3

Added some new functions:

• dateInfluence, which works out how influential a single date is in acore
• coreInfluence, which tries to estimate the total uncertaintyreduction/increase between two Bchronology runs
• choosePositions, which suggest new positions/depths to date tomaximally reduce uncertainty
