Changes in version 0.9.26.9000-73 (2024-11-27)

New functions

• calc_EED_Model() models incomplete and heterogeneous bleaching of mobile grains after Guibert et al. (2017). Along with the function, the new ExampleData.MortarData data set was added.

• fit_DoseResponseCurve() and plot_DoseResponseCurve() are two new functions derived from plot_GrowthCurve(): the first only performs the fitting of a dose-response curve, while the second plots it. This brings greater flexibility and increased speed, as plotting is now independent of fitting (#141, fixed in #318).

• melt_RLum(): Creates a new flat data.frame from the objects that can be used for instance in combination with 'ggplot2'. Works only on RLum.Data.Curve-class and RLum.Analysis-class objects and lists of such objects.

• merge_RLum.Data.Spectrum(): This new function allows to merge two or more RLum.Data.Spectrum objects in different ways (#368, fixed in #419).

• view(): A short cut to the utils::View() spreadsheet-like data viewer tailored to the objects in the package.

Breaking changes

• We have dropped our dependency on the readxl package: functions analyse_baSAR() and use_DRAC() now do not accept XLS files anymore but CSV files instead (#237, fixed in #270). CSV files can be easily generated from XLS files by Excel or similar applications, or by reading them with readxl::read_excel() and saving them with write.csv().

• The plot.single option, which was available for several functions, sometimes under a slightly different name, has now been renamed to plot_singlePanels for overall consistency and clarity. Function scale_GammaDose() used that option but gave it the opposite meaning: now also this function conforms to the rest of the package. The use of the older names is now deprecated and will produce a warning (#351, fixed in #408).

Removed functions and deprecations

• Function Analyse_SAR.OSLdata() is now officially deprecated, analyse_SAR.CWOSL() should be used instead (#216, fixed in #264).

Bugfixes

analyse_al2O3C_CrossTalk()

• The function doesn’t crash anymore if option recordType is specified and none of the records in the data set is of that type (#487, fixed in #488).

analyse_baSAR()

• Argument XLS_file has been replaced by CSV_file and, as mentioned above, the function now only accepts CSV files as input (#237, fixed in #270).
• Add support for recordType passed to get_RLum in the additional arguments.
• Option plot.single has been renamed to plot_singlePanels (#351, fixed in #408).
• The function crashed if the number of MCMC iterations was set equal to the thinning interval; on the other hand, we saw errors reported from JAGS if the number of MCMC iterations was not at least double the thinning interval. To address this, we slightly retouched our automatic setting of the thinning interval (which was problematic only if the number of MCMC iterations was extremely low); on the other hand, if a user sets a thinning interval that is too high, we now reset it to a lower value and raise a warning (#407, fixed in #409).
• The function crashed if a Risoe.BINFileData-class object was provided with and the argument irradiation_times was set; fixed.
• The function was supposed to remove non-OSL curves from the dataset, well it almost never did; fixed.

analyse_FadingMeasurement()

• The function now checks for the version of the BIN-file that originated the RLum.Analysis object given as input, and reports a message if a version older than 5 was used (#281, fixed in #282).
• The function doesn’t crash anymore on some RLum.Analysis input files (#283, fixed in #288).
• Option plot.single has been renamed to plot_singlePanels (#351, fixed in #408).
• The function doesn’t crash anymore if no record is left after removal of records with negative time since irradiation (#454, fixed in #456).

analyse_IRSAR.RF()

• The performance of this function has been improved for the “SLIDE” and “VSLIDE” methods, thanks both to tweaks in the C++ implementation of the sliding algorithm and in how that is managed on the R side. In particular, the default number of sliding windows tested in the algorithm has been reduced from 10 to 3: this value is no longer hardcoded, but can be tuned through the new num_slide_windows setting (part of the method.control option), thus allowing to find a balance between computation time and quality of fit (#372, fixed in #388, #398 and #399).
• The function is more robust against sequence_structure misspecifications (#393, fixed in #394).
• Some data preparation steps where not correctly applied for method = "VSLIDE" (#396, fixed in #397).
• Option method.control has been renamed to method_control for consistency with all other functions in the package (#411, fixed in #412).

analyse_pIRIRSequence()

• Option plot.single has been renamed to plot_singlePanels (#351, fixed in #408).

analyse_SAR.CWOSL()

• Option plot.single has been renamed to plot_singlePanels (#351, fixed in #408).

calc_CentralDose()

• Argument na.rm is now deprecated: the function will now always remove missing values, as otherwise the presence of any NA would propagate and produce unusable results (all NAs) or buggy behaviour (#302, fixed in #304).
• The function stops the fixed-point iteration for the computation of the profile log-likelihood as soon as sigma < 1e-16, as allowing sigma to become zero leads to infinities and buggy behaviour (also fixed in #304).

calc_FastRatio()

• A number of crashes related to input validation have been fixed (#471, fixed in #472).

calc_gSGC()

• The function crashed if the data contained negative errors: to avoid this, we now take the absolute values of errors (#479, fixed in #481).

calc_IEU()

• The code of this function has been consolidated to avoid duplication and make its debugging easier: this has uncovered a small coding error and also led to some speed up (#429, fixed in #430, #431 and #432).
• Some crashes in the function have been solved (#424, fixed in #433).

calc_Lamothe2003()

• We addressed a long-standing issue regarding the calculation of the Ln/Tn error after fading correction, which led to smaller than expected errors (#96, fixed in #296).

convert_RLum2Risoe.BINFileData()

• The function could crash with a incompatible types (from raw to character) error under particular circumstances; fixed.
• The function would also fail in edge cases where different objects are mixed so that certain fields for METADATA are already available, however, in the wrong format; fixed

extract_IrradiationTimes()

• In some circumstances the function failed to update an existing BIN/BINX file due to an incorrect way of subsetting an intermediate data frame of results (#445, fixed in #446).

get_RLum()

• If get_RLum() with subset was used on info objects of an RLum.Analysis-class object it would return wrong results if the info element was not present in all records; fixed.

import_Data()

• The function automatically determines the available import functions and ensures that formats supported by the package are tested and used.
• A minor change in the code enables the support of character vector of length > 1 as input (e.g., different file names). Further, the function got tested against a mixture of input formats. Means, you can provide many different files formats and they function will try to import them all in one go.

plot_DetPlot()

• Option plot.single has been renamed to plot_singlePanels (#351, fixed in #408).

plot_DRTResults()

• The function crashed if option na.rm was used alongside the preheat option but the data set contained no missing values (#474, fixed in #475).

plot_GrowthCurve()

• The function is now implemented as a wrapper around fit_DoseResponseCurve() and plot_DoseResponseCurve(). There should be no visible user-facing changes (#319, fixed in #322).
• Support new ... arguments for plotting (implementation in plot_DoseResponseCurve()) for legend (turn on/off legend) and reg_points_pch for fine grained control over the point shape.
• Add density_polygon, density_pologyon_col, density_rug, box as ... arguments to plot and add respective plot options
• The function crashed for single grain data that sometimes cause a lot of NaN values during log conversions required for estimating the start parameters. The result was the error object 'b.MC' not found (#374; fixed)
• For the non-linear choices of fit.method ("EXP+LIN", "EXP+EXP", "GOK" and "LambertW"), the function could get stuck in an endless loop when the number of parameters was larger than or equal to the number of data points. This is now checked, and in those cases the method is changed to "LIN" (#381, fixed in #465).
• We replaced nls() with minpack.lm::nlsLM() as it’s more robust and can find a fit in cases where nls() would fail. Please keep in mind that it does not mean that fit results in those cases make any sense, it just helps to avoid uncontained events in the R session (addresses #381).
• Option output.plotExtended.single has been renamed to plot_singlePanels (#351, fixed in #408).
• The function now supports a list of data frames as input, in which case it calls itself on each element of the list and produces a list of RLum.Results as output (#405, fixed in #434).

plot_RLum.Analysis()

• Option plot.single has been renamed to plot_singlePanels (#351, fixed in #408).

plot_RLum.Data.Curve()

• Argument norm is now better validated so that specifying an incorrect value returns an error instead of silently skipping curve normalisation (#250, fixed in #263).

plot_RLum.Data.Spectrum()

• The gradient between colours when plot.type = "persp" is now more consistent and doesn’t produce artefacts in the regions of transition between colours (#371, fixed in #380).
• The function would crash if the bin.rows or bin.cols value was set too high or if xlim and ylim were set too tight (#415, fixed in #416).

read_BIN2R()

• The function is now much faster: we have recorded an overall improvement of over 60% on a 46M file, with potentially bigger time savings for larger files (#298, fixed in #333, #355 and #360).
• Argument n.records is now better supported for BIN files v3 and v4 and doesn’t lead to a crash when used in conjunction with the fastForward option (#343, fixed in #344).
• Argument zero_data.rm was not correctly propagated if the input object was provided as a list (#342, fixed in #345).
• The METADATA fields that are not actually read from the BINX file in case of a ROI record are now set to NA rather than being assigned the value from the previous record (#336, fixed in #360).
• The .RESERVED slot is now kept in sync with the rest of the object when records are dropped from the input BIN/BINX file (#337, fixed in #348).
• The function doesn’t crash anymore when reading a file that contains a record with an unrecognised version after other records with a valid version have been read (#352, fixed in #353).
• The function doesn’t crash anymore when reading a file that contains a ROI record while using fastForward = TRUE (#356, fixed in #360).

read_XSYG2R()

• The new n_records argument now enables to control the number of records to import, which can be useful in case the file is faulty.
• The function sometimes struggled with the import if only a directory was provided; fixed.
• The function truncated the terminal output under certain circumstances; fixed.

scale_GammaDose()

• Option plot_single has been renamed to plot_singlePanels and was changed so that plot_singlePanels = TRUE will produce one plot per panel, as it would happen for other functions (#351, fixed in #408).

template_DRAC()

• The function gained a new argument file_input that enables the creating of a DRAC template based on an existing DRAC CSV file. This way, already available DRAC files can be conveniently modified without having to call use_DRAC() first.
• The template contained a couple of minor mistakes that got fixed along with a more strict enforcement of the class of each field, which is now set as an attribute; the change should have no user-visible effect.
• The function now supports the conversion factors by Cresswell et al. (2018) (Cresswelletal2018). Please ensure that the server supports that option.

trim_RLum.Data()

• The function has been made more robust against misspecifications of its trim_range argument that could lead to crashes (#460, fixed in #461).

use_DRAC()

• Support for DRAC v1.1 XLS/XLSX files has been dropped, users should use CSV files according to the DRAC v1.2 CSV template.
• The function gained support for three new ... arguments: version_ignore to ignore the DRAC version check, user and password to access password protected websites.
• The identifiers submitted to the DRAC server are now better randomized to to guarantee more confidentiality of the data transmitted (#435, fixed in #438).

verify_SingleGrainData()

• Potentially breaking old code!: if cleanup = TRUE the result was not consistent and produced a mixture of RLum.Results and RLum.Analysis/Risoe.BINFileData objects in particular when run over a list, this was not what stated in the manual. Now the function indeed cleans up the object, hence if a list of RLum.Analysis objects is provided, the result is a cleaned list of that object. If the clean-up means that the everything was removed, the result is NULL. * Improve warning messages; it was indeed not very intelligible.
• The function doesn’t crash anymore when applied to an empty list (#365, fixed in #366).
• Silence the very talkative terminal output even if nothing was removed from a record for cleanup = TRUE.
• The function now provides better terminal feedback if the selection results in an empty record.
• Add a new logical argument use_fft that will apply an additional Fast Discrete Fourier Transform (FFT) verification on the data if wanted.

write_R2BIN()

• The function now supports the verbose argument, which can be used to suppress output to the terminal (#442, fixed in #444).

Internals

• get_DRAC_references() now works also on a DRAC.list got updated references.
