Changes in version 0.9.26 (2024-11-18)

Removed functions

• Function calc_Kars2008() (deprecated since version 0.8.1) is now officially defunct, calc_Huntley2006() should be used instead (#252, fixed in #257).

Bugfixes

analyse_pIRIRSequence()

• The function crashed with a object merge error if run in a loop because of a merge_RLum() error. This was caused by a regression while implementing the n_N calculation in plot_GrowthCurve(). Potentially affected was also analyse_SAR.CWOSL().
• The function now shows a warning and sets plot = FALSE when option plot.single = FALSE is set but the device size is too small. This should prevent “Figure margins too large” errors.
• The function will not crash anymore during the plotting in another edge case related to single grain data.

analyse_SAR.CWOSL()

• The function crashed for mixed set of RLum.Analysis-class objects typically observed for single grain data, e.g., one object contains only TL curves while all others contain the OSL/IRSL data from the grain. As the function filters those records automatically, it crashed because the aliquot number assignment internally relied on the length of the object (regression, #373, fixed)

analyse_SAR.TL()

• The function now produces a more correct rejection.criteria data frame (#245, fixed in #246).
• Several edge cases that led to crashes have been fixed (#147, fixed in #247).

get_RLum()

• When the function was used on a list of RLum.Analysis-class objects with the argument null.rm = TRUE it would remove all NULL objects, but not elements that became list() (empty list) during the selection; fixed.
• Fix an edge case that caused a rather non-expected, more visible output problem. When curves were selected via recordType on RLum.Analysis-class objects (or a list of them) containing only a single RLum.Data-class object, the function returned the RLum.Data.Curve-class object regardless of the selection in recordType. In other words: if a user tried recordType = "TL" on an RLum.Analysis-class object that contained only a single IRSL curve, the function would still return that single IRSL curve instead of an empty element. The reason for this behaviour was a poor attempt to deal with NA in the recordType name that led to missing values and unexpected behaviour for a logical comparison. Now, before the subset happens, NA values in recordType are converted to "NA" (a character), allowing us to fix the incorrect subsetting.

plot_RLum.Data.Spectrum()

• Add support for lphi and ltheta light direction arguments for plot.type = "persp".
• Fix the reason for the unclear warning In col.unique == col : longer object length is not a multiple of shorter object length

write_R2BIN()

• Recently, non-ASCII characters in comments or file names have become more common and that led to crashes during the file export. To avoid this, now all non-ASCII characters are replaced by _ before writing them to the BIN/BINX files.
• The function now returns the file path of the export.
• Fix a bug that left connections open if the function crashed.

Internals

• Two new internal functions .throw_warning() and .throw_error() sometimes flushed the terminal with messages if called (internally) in particular circumstances. Now we maintain a stack of function names, so that at any time we can report correctly the name of the function where an error or a warning is thrown (#254, fixed in #256).

Changes in version 0.9.25 (2024-09-12)

This package version requires R >= 4.3

New functions

• read_HeliosOSL2R(): New import function to support the new zero rad Helios luminescence reader and its .osl file format. The output is an RLum.Analysis-class object.

Bugfixes

analyse_baSAR()

• Fix #183 addressing an edge-case crash when the function was called on an object containing no records of the appropriate type (#184, 1).

analyse_FadingMeasurements()

• Add ... support to disable the blue trend line via plot.trend = FALSE
• Fix #175 to deal gracefully with the case when the size of Lx and Tx doesn’t match (#192, 1).

analyse_portableOSL()

• Function did not respect argument main; fixed.

convert_Wavelength2Energy()

• Fix #133 addressing cases where R throws an uncontained error when R drops the object structure in very rare cases (#134; thanks

calc_Huntley2006()

• Improve success rate of GOK fitting of the unfaded data using a two step approach: first an exponential fit is applied then this values are used as start parameters.

calc_Statistics()

• The skewness and kurtosis depended on number of MC samples (#122); fixed with #123 (thanks to 1)

calc_TLLxTxRatio()

• Function crashed for Tx.data.background = NULL (#129); fixed with #130 thanks to 1

calc_WodaFuchs2008()

• The function now officially supports numeric vectors and single-column data frames as input (#200).
• The function computed the number of breaks for the histogram incorrectly (#197, fixed with #198).
• The function now supports more types of RLum.Results objects without crashing, although if the object contains only one data point it will stop immediately to avoid problems with nls() (#199, fixed in #219).

extract_IrradiationTimes()

• If a BIN/BINX-file is provided, the function will now check that it contains the same amount of data as the corresponding XSYG file a bit earlier than before, thus avoiding a possible crash (#228, fixed in #229).

fit_CWCurve()

• Argument output.path has been removed, and a warning is raised when attempting to use it (#207, fixed in #209).

fit_EmissionSpectra()

• Parameter input_scale was not correctly propagated when the function would self-call (#160, 1).

fit_OSLLifeTimes()

• The validation of the minimum dataset size didn’t account for the use of the signal.range argument (#182, fixed by #195, 1).

fit_SurfaceExposure()

• Fix #162 to remove a dimension mismatch if the input data contained NAs, which would generate unexpected warnings (#163, 1).
• The function doesn’t stop anymore with an error if called on an RLum.Results object (#165, 1).

plot_AbanicoPlot()

• Argument plot.ratio will now throw an error on non-positive numerical values (#221, fixed in #222).
• The function doesn’t crash anymore when setting interactive = TRUE (#220, fixed in #233).

plot_DetPlot()

• Argument signal.integral.max is now enforced to be greater than signal.integral.min, as otherwise the computation of the number of channels would produce Inf (#203, fixed in #206).
• Fix a crash when using option analyse_function = "analyse_pIRIRSequence" (#210, fixed in #211).

plot_GrowthCurve()

• The function now calculates the relative saturation (n/N) using the ratio of the two integrates. The value is part of the output table.
• Argument na.rm has been removed: as of version 0.9.23, it was defunct and only accepted TRUE as valid value and produced an error otherwise, so there is no effective change in behaviour (#137, fixed in #214).

plot_Histogram()

• The function doesn’t crash anymore when setting interactive = TRUE (#186, fixed in #231).

plot_KDE()

• It now officially supports numeric vectors and single-column data frames, for which it assumes that the De error at each measurement is 10^-9 (#189, fixed in #194, 1).

plot_NRt()

• The function reports an helpful message rather than crashing when applied to an object of unexpected type or when there is a mismatch in time values (#177, fixed with #179 by 1).

plot_RadialPlot()

• The function doesn’t crash anymore when a single-column data frame is provided (#191, fixed in #212).

plot_RLum.Data.Analysis()

• The function now supports all arguments from plot_RLum.Data.Spectrum(); before it had only basic functionality for RLum.Data.Spectrum-class data.

plot_RLum.Data.Spectrum()

• The plot function can now handle non-increasing column values for plotting (with a warning).

read_BIN2R()

• ignore.RECTYPE now supports numeric values, e.g., 128. Records for this type will be ignored during import.
• BINX-files with RECTYPE = 128 will not crash anymore, thanks for asking Anna-Maartje Boer and replying Karsten Bracht.
• The function now stops graciously when attempting to read an empty file (#225, fixed in #226).

read_PSL2R()

• The function is out of the beta status, hence the flag was removed.
• The RLum.Analysis-class object returned by the function gained a new element Sequence, which is a data frame. with the measured sequence. This way, if the original sequence was lost, it can still be extracted from the .psl data.
• If no .psl file was found the function got trapped in an infinite loop (#127); fixed with #128 (thanks to 1)

read_XSYG2R()

• Fix spectrometer data import for basically broken files.

read_Daybreak2R()

• Fix #135 to improve detection of non-ASCII files (#140, 1).

Risoe.BINfileData2RLum.Analysis()

• Fix a crash when reading an empty Risoe.BINfileData input (#215, fixed in #224).

Internals

• New internal function + tests added .get_named_list_element(). It just does what the names says.

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.
