rcarbon v.1.3.0

• UPDATEs in modelTest():
  • Added an error message and a note in the help documentation warning users to not use calibration curves not supported by uncalibrate().
  • NEW argument gridclip to add range constrain in the simulation envelope. When set to TRUE the sampling is executed within the observed range of dates.
  • UPDATE timeRange can now be left undefined, in which case the range of median calibrated observed dates is used.
  • NEW argument normalised handles whether simulated dates should be normalised or not.
  • NEW arguments backsight and changexpr enabling the comparison of expected and observed rates of changes.
  • UPDATE: improved performance of calsample and uncalsample methods (update in uncalibrate()) `
  • Bug fix: users no longer need to specify nsim when fitonly is set to TRUE.
• UPDATE in permTest()
  • NEW arguments backsight and changexpr enabling the comparison of expected and observed rates of changes.
• UPDATE in spd(): aggregation matrix now spans beyond timeRange to avoid edge effects.
• UPDATE in calibrate(): the new argument F14C enables calibration in F14C space.
• UPDATE in SPpermTest():
  • function is deprecated and renamed sptest()
  • function now allows user defined expression for computing the rate of change
• UPDATE in spd2gg():
  • function is deprecated and renamed spd2rc()
  • function now allows user defined expression for computing the rate of change
  • rates of changes can now be based on abutting time-blocks (e.g. 5600-5501 to 5500-5401) or a fixed interval across all years.
• NEW: thinDates() function to randomly select a maximum number of dates per site, bin or phase.
• NEW: as.CalDates() function converts dates in BchronCalibratedDates class (Bchron) and oxcAARCalibratedDatesListclass (oxAAR) into CalDates` class (rcarbon).
• NEW: sampleDates() function for sampling random dates from calibrated dates or bins.
• NEW: ckde() function for generating composite kernel density estimates.
• NEW: Suite of functions for mapping the spatial intensity of a set of radiocarbon dates via Kernel Density Estimates.
  • stkde() Map the spatio-temporal intensity of a set of radiocarbon dates across multiple years
  • spkde() Map the spatial intensity of a set of radiocarbon dates for a given focal year.
  • Associated plot() function.
• NEW: subset() and which.CalDates() for subsetting and extracting indices of calibrated dates based on temporal intervals described by logical conditions (e.g. between 5500 and 4500 cal BP) and user defined probability mass.
• Bug fix: fixed display error in some plot() functions when calendar is set to `BC/AD'
• Bug fix: fixed error in the computation of the combined uncertainties in mixCurves().
• Further minor bug fixes for R 4.0.0
