rplum 1.0.0

• updated to rbacon 3.5.2 (which changes how greyscale images are plotted). Removed temporary code copied from rbacon code that caused issues with plotting.

rplum 0.5.2

• it is now an error if no radium measurements are provided (ra.case=0) while n.supp is set to 0
• through rbacon (version >=3.4.1), posterior values for phi and supported are now provided
• to plot depths beyond where background has been reached, use both d.max and remove.tail=FALSE
• radiocarbon ages can now be entered as F14C or pMC values (e.g. for postbomb dates). Please indicate using the F14C or pMC option which ones are in F14C/pMC (e.g., Bacon(F14C=2:4) if dates 2 to 4 are in F14C). These values will then automatically be rewritten as C14 ages within the C14 .csv file.
• When running Plum as tmp <- Plum(save.info=FALSE), no additional variables beside ‘tmp’ will be saved in the session. For subsequent calculations, provide ‘tmp’, e.g. as in Bacon.hist(20:40, set=tmp). The default remains to save an object ‘info’ to the session, and this object will then be used to make any further calculations using set=get('info').
• rbacon 3.4.1 has some issues in draw.pbmodelled (related to plotting bluescale images), PlotSuppPost (should calculate mean(unlist(set\(ps)) instead of mean(set\)ps)) and agedepth (doesn’t place the results of draw.pbmodelled into set). So we’re temporally placing updated versions of these functions in the file ‘frombacon.R’ until the next version of rbacon (probably 3.4.2) is on CRAN.

rplum 0.5.1

• further measures to link to the new ‘rice’ package (and not ‘rintcal’)

rplum 0.5.0

• save.ages has been renamed to save.elbowages (for consistency with rbacon)
• ‘olderthan’ and ‘youngerthan’ ages can now be used (only non-210Pb)
• now links to the new ‘rice’ package
• if there are 7 or fewer data points, a warning will be provided (instead of an obscure error). This has to do with there being a need for at least 4 datapoints to estimate background levels

rplum 0.4.0

• repaired a bug which crashed the session if cc=4 was specified
• renamed ccdir to cc.dir
• youngest.age and date.sample now work more robustly
• rplum now requires at least rbacon’s version 3.2.0 (corrects bugs with postbomb dates and with the naming of cc.dir)
• renamed the options MinAge and MaxAge to the hopefully less confusing youngest.age and oldest.age

rplum 0.3.0

• now uses the renamed rintcal package instead of the IntCal package
• any non-210Pb dates are now drawn in more predictable colours
• in case of hiatuses, plots are now done as expected
• tail measurements are now dealt with better (no extrapolation beyond reasonable territory)
• information is provided on ballpark accumulation rates and how they compare to the prior settings
• If the depths in the dets file appear not be the bottom depths of the slices, this now results in an error

rplum 0.2.2

• removed closeAllConnections() option as requested by CRAN
• if there is only one date in otherdates (e.g., a historical Cs peak), acc.rate isn’t set to overly low values any more
• added a function to estimate how many iterations will be run and returned

rplum 0.2.1

• further separation of rbacon and rplum
• added LL14, a core with Pb-210, radon and C14 dates (core kindly provided by Dr Lysanna Anderson, USGS)
• many sundry bug fixes related mainly to plotting

rplum 0.2.0

• now depends on the rbacon c++ code instead of carrying a duplicate of the code. Same for many of rbacon’s internal functions for plotting etc.
• now depends on IntCal package for radiocarbon calibration curves
• now only calculates the age-depth model for Pb data that are above background level
• enhanced how to take into account different scenarios with radon.case and n.supp

rplum 0.1.5.1

• removed vignettes as they threw errors which made the package unacceptable by CRAN

rplum 0.1.5

• updated to the latest radiocarbon calibration curves IntCal20
• repaired a bug with plotting when using BCAD=TRUE
• reduced sizes of files of example cores
• removed inset option for now as it caused many post-plotting issues

rplum 0.1.4

• clarified author names
• replaced cat() by message() or warning() where possible
• lots of minor bug fixes related to plotting and post-run analysis

rplum 0.1.3

• added single quotes to package names as requested by CRAN maintainer
• further clarified copyright statements

rplum 0.1.2

• clarified copyright statements

rplum 0.1

• first version of the ‘rplum’ package, developed from ‘pyplum’ at https://github.com/maquinolopez
