Bchron 4.7.6

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

Bchron 4.7.5

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

Bchron 4.7.4

• Updated the BchronDensity and BchronDensityFast functions to show lines on top of dates
• Included ability in above functions to change amount of date transparency
• Used styler to make the syntax follow tidyverse style guidelines
• Fixed bug in starting values which occasionally produced values before the extractDate
• Fixed bug in choosePositions where position chosen was at the edge of the domain

Bchron 4.7.3

• Fixed a weird bug where some hdrs were coming out the wrong way in plot.Bchronology
• Add the ability to create OxCal style plots with the calibration curve
• Added a feature to plot individual dates in plot.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 to have incorrect error ranges compared to OxCal
• Fixed a problem that occurred in very straight chronologies where a certain 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 a core
• coreInfluence, which tries to estimate the total uncertainty reduction/increase between two Bchronology runs
• choosePositions, which suggest new positions/depths to date to maximally reduce uncertainty
