merge_RLum.Data.Curve()
: Function allows merging of RLum.Data.Curve
objects in different ways (#128).
RLum.Analysis-class
:
Show warnings messages when empty object are produced by a get_RLum.Analysis()
request (implemented in get method and show method).
analyse_SAR.CWOSL()
rename argument output.plot
to plot
,
rename argument output.plot.single
to plot.single
,
rejection criteria added 'De > max. dose point'. These avoids that values are accepted even the De from the fitting should be considered as invalid.
analyse_IRSAR.RF()
Add enhanced support for ...
, e.g. log
, xlim
, ylim
,
rename argument output.plot
to plot
.
analyse_pIRIRSequence()
Fix an error that causes problems during plotting (Error in plot.new(): figure margins too large),
rename argument output.plot
to plot
,
rename argument output.plot.single
to plot.single
.
merge_RLum()
: Function extended accordingly with the newly implemented function
merge_RLum.Data.Curve()
(#128).
plot_AbanicoPlot()
:
ticks removed from error bars,
line value output removed,
placement of y- and z-labels set to center of plot,
weights-option for KDE integrated,
warning for linear z-scale removed,
fixed an error that occured in Abanico Plot for a large data range (#188),
function output extended by data points in/out of confidence interval,
histogram option added,
dot plot option added,
KDE bandwidth added to plot output,
KDE bandwidth default changed to "SJ",
rugs coloured according to subsets,
examples section extended.
plot_GrowthCurve()
:
Thanks to a querry from Rachel Smedly (#194) the De error calculation method has been updated. So far only the Lx/Tx values have been re-sampled using a Monte Carlo simlation approach to estimate the error. In contrast to the Analyst the Ln/Tn value was just considered without any error. This has been changed for all fitting methods and the final De error is calculated now also using the Ln/Tn error. Note: Usually this change results in a larger De error, however this approach is much more realistic,
consequently to the changes made in the error calculation the corresponding De resulting from
the MC simulation is now added to the output object ($De$De.MC
),
Ln/Tn point including the error is now added on the plot output as red circle,
fix a bug occasionally occurred for fit.method = "EXP+EXP"
and the function broke
subsequently (#159).
readBIN2R()
:
critical bug fixed: GRAIN
and GRAINNUMBER
were not imported properely
(thanks to Norber Mercier),
import speed has been improved by at least an order of magnitude, due to a different
internal data handling (using of data.table
instead of data.frame
). This may become
relevant for hugh BIN-files like they are produced by single grain measurements (#191).
Note: The Risoe.BINfileData-class
remained untouched.
writeR2BIN()
:
minor changes due to the changes in the function readBIN2R()
,
confusing warnings during writing are suppressed.
Add new dependency for package data.table
(used in the function readBIN2R()
).
Amongst a few minor changes with this release we continued the homogenisation process to further unify our function arguments. So far meaningful similar function arguments can be used over all functions in the package to produce similar effects (e.g., na.rm = TRUE/FALSE). For you as package user it means that self-written R scripts using package functions are likely to break. Please check the list of changes below.
We apologise for any inconvenience!
RLum.Data.Image
: S4-class for handling image data including. Image
data in slot data
are stored as RasterBrick
RLum.Results
: homogenised structure for containing the following base items in the
slot data: 'summary', 'args' and 'call'. Where applicable the 'data' slot contains the original input data.
Depending on the function various further slots are added containing additional (intermediate) data and objects,
set_RLum.Data.Image()
: Set method for class RLum.Data.Image
get_RLum.Data.Image()
: get method for class RLum.Data.Image
further: corresponding show and coercing methods added for class RLum.Data.Image
.
analyse_pIRIRSequence()
: Function to analyse post-IR IRSL sequence
measurements (#133),
calc_MinDose()
: the previous calc_MinDose3()
and calc_MinDose4()
functions were merged to the new calc_MinDose()
function, which was rewritten from
scratch and now contains both the 3- and 4-parametric
Minimum Age Models (introducing the new argument par
).
Detailed changes and bugfixes are listed further below,
calc_MaxDose()
: a wrapper function that calls calc_MinDose()
,
but transforms the data set similar to the method described in Olley et al. (2006).
Rather than estimating the minimum dose of a De distribution, this function estimates the maximum dose.
calc_SourceDoseRate()
: calculating the dose rate of the irradiation source at the
date of measurement based on: source calibration date, source dose rate, dose rate error.
get_Layout()
: Helper function to return a list with layout definitions for
more homogenous plotting,
get_RLum()
: Wrapper function for various get methods for RLum
-objects (#148),

of objects an RLum.Analysis object consists of (#138),
merge_RLum()
: Wrapper function for various merge methods for RLum
-objects (#139),
plot_RLum.Data.Image()
: Plot function for RLum.Data.Image
object.
Function also added to wrapper function plot_RLum
,
plot_RLum.Results()
: Plot function for RLum.Results
objects.
RLum.Results objects created, e.g. by the age model functions may now be passed to plot_RLum.Results()
to create specific plots that previously were generated by the functions themselves.
Function also added to wrapper function plot_RLum
,
readSPE2R()
: Add support Princenton Instruments *.SPE files
(camera and spectrometer measurements). Function output is a RLum.Data.Spectrum
or RLum.Data.Image
object.
ExampleData.RLum.Data.Image
: Example data for RLum.Data.Image
object
(part of #135).
get_RLum.Analysis()
: Add support for inverse record.id
selection, e.g. record.id = -1
selects
all objects except the first.
get_RLum.Results()
:
Add support for data objects for objects
produced by the function calc_OSLLxTxRatio()
,
match access behavoir of objects produced by the function
calc_TLLxTxRatio()
. Now it works similar to the function calc_OSLLxTxRatio()
.
Risoe.BINfileData-class
: Description updated due to established changes
made for a better file format support.
Risoe.BINfileData2RLum.Analysis()
: If the pos
value
is invalid now the function does not return an error any longer. Instead
NA
is returned.

,
argument method
added to allow selection between the method "FIT"
and
"SLIDE"

enhance argument output.plot.single
for numerical values.
This allows to select each single plot output individually,
details from the argument rejection.criteria
were removed
from the argument list to allow a more flexible handling (e.g. changing only
one parameter at time) and to clean up the argument list. However, the argument
work still as excpected (#145),
reformat of rejection criteria output to allow easier further treatment,
support graphical output of rejection criteria and IRSL curve (if exists),
minor bug fixes (e.g., not properly caluculated TL curve resolution) and graphical adjustements.

:
support of data without given uncertainties.
calc_Statistics()
:
support of data with NA

plot_DRTResults()
:
Argument na.exclude
renamed to na.rm
,

are not required any longer (became an optional argument).
With this the plot function can be easily re-used, e.g. for preheat plateau tests,
change behaviour of the argument na.rm
. If a data set is provided containing
NA
values also the corresponding values in provided by the argument preheat
are
cleaned up. This allows a proper usage of the function in combination with grouping option
(e.g., boxplot = TRUE
,
add argument par.local
to allow to combine output plots in broader plot
frameworks,
minor corrections in error handling and graphical appearance.

bug for small values fixed, rounding to 0 decimals replaced by 3 significant digits,
individual statistical summary order supported (#184),
minor fixes for the graphical output.
plot_RLum.Analysis()
:
Add argument abline
to allow inserting similar vertical or horizontal lines
in every plot. The decision to implement this argument in this function instead the function
plot_RLum.Data.Curve()
was made because in a single plot modus abline
is more
sufficiently used as separat function call,
now reset par
parameters suffciently,
add argument combine
to allow fast combining of curves in single plot window.
plot_RLum.Data.Curve()
:
Add argument norm
to allow for curve normalisation to
the highest value (#129),

was set
in a way that only one wavelength (colour value) was remained,
correct zebra-colour-pattern for rare cases of xlim
settings
using plot.type = "persp"
or plot.type = "persp3d"
,
add argument new plot type "transect"
for plotting a transect
along the time/temperature axis for a specific wavelength/channel intervall
(#120, requested by Regina DeWitt),
correct function break for a single column matrix (single frame spectrum)
by automatically resetting plot.type
to single
for single frame spectra,
colour rug (rug = TRUE
) implemented for plot type "multiple.lines"
(#130),
argument xaxis.energy
for wavelength energy conversion for
2D plots added (#141).
readBIN2R()

complete format support as now a more throughtful distinction is made between
version 03 and 04 (also made for function writeR2BIN()
) (#182),

element during import.
With this, previous curve selections made with other software are kept
(#181, Norbert Mercier).

:
If the stimulator is infrared light the recordType
will be set to IRSL
. This
makes the curve types more consistent with the commonly applied nomenclature,
now the function automatically converts time values to temperature values also
for spectra data (#121); behavious is triggered with the argument recalculate.TL.curves
.
Second2Gray()
:
Minor code and example adjustments in along with creating a new function
calc_SourceDoseRate()
(#56).
writeBIN2R()
:
Complete format support as now a more throughtful distinction is made between
version 03 and 04 (also made for function readBIN2R()
) (#182),
SEL
will now be kept using the TAG
bit, releated to changes made
in function readBIN2R
(#181, Norbert Mercier).
Add new dependency for package raster
and sp
, which is used
for the RLum.Data.Image-class
,
dependency to package 'Rserve' removed,
dependcy to package 'zoo' added (used for running means),
dependency to package 'bbmle' added (used for maximum likelihood estimations).
