In crp2a/gamma: Dose Rate Estimation from in-Situ Gamma-Ray Spectrometry Measurements

gamma 1.0.5.9000

Bugfixes

• Fix an error in the uncertainty calculation of dose_predict. The returned error was too large and did not make much sense due to an internal calculation error. Along with the fix, the manual was updated to detail the uncertainty calculation. (PR #42 by @RLumSK)
• Fix a graphical issue where the peaks were peaks were set with set_energy() but did not show correctly when plotted using the standard plot method, e.g., plot(cal, pks) would show only observed but not expected energy lines in the secondary x-axis. Now the expected energy lines (if set) are show. (#29, PR #32 by @RLumSK).
• Fix the uncertainty calculation for the integrated signal. The formula had an factor of 2 in var(2 * x) where x is the integrated signal. Now the formula considers plain Poisson statistics. Along with this change, the calculation is now detailed in the manual (PR #46 by @RLumSK).

Additions

• Add support for Kromek SPE files to read()(#28 by @RLumSK).
• Add support for GammaSpectra-class objects for energy_calibrate()(issue: #22, PR #31 by @RLumSK).
• Add coercion method for PeakPosition-class to list (exported as as.list()) and from list to PeakPosition-class. This enables better plotting functionality if the peak positions for where provided manually as list and not via, e.g., peak_find() (PR #37 by @RLumSK).
• Add additional columns to the output object of dose_predict() and calculate a "final" dose based on the mean of the findings from the count and the energy threshold (PR #43 by @RLumSK)
• Add new argument use_MC to dose_predic() method. The default is FALSE to maintain compatibility with old code and output exceptions. If set to TRUE the uncertainty on the gamma dose rate uses a Monte Carlo simulation approach for a more realistic error estimation (PR #46 by RLumSK)
• Extend dose_predict() to work with a numeric input for background as claimed in the documentary. This value can also be set to c(0,0) if no background subtraction is wanted (PR #38 by @RLumSK)

Changes

• Update vignette about the dose rate calibration curve determination to make it more intelligible (#30 by @RLumSK).
• Update manual for the output object of dose_predict(), which had some loopholes (PR #43 by @RLumSK)

Datasets

• Add conversion factor reference to clermont dataset for better transparency.
• Add new dataset called clermont_2024 based on the original clermont dataset but with dose rate conversion factors and gamma dose rate calculated for different conversion factor datasets (PR #40 by @RLumSK)

gamma 1.0.5

Internals

• Fix unicode character in plot axis labels.

gamma 1.0.4

Bugfixes & changes

• Fix the metadata when reading a CNF file: do not use a fixed index to isolate particular metadata (the number of metadata may vary depending on the user's acquisition).
• Fix set_energy<- so that argument value appears in the method at the end of the argument list.

gamma 1.0.3

Bugfixes & changes

• Remove the alpha argument in dose_fit() to follow changes in IsoplotR.

gamma 1.0.2

Internals

• Use testthat 3rd edition (#20).
• Change package maintainer (#24).
• The package was removed from CRAN due to an internal call to a defunct function default.stringsAsFactors(); fixed (#23, @RLumSK)

gamma 1.0.1

gamma 0.2.0

• Beta release.

gamma 0.1.1
