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

These binaries (installable software) and packages are in development.
They may not be fully stable and should be used with caution. We make no claims about them.
