Changes in version 0.9.19 (2022-03-10)

This package version requires R >= 4.0.5

New functions

  • extract_ROI(): Light-weighted function to extract pixel values
    from pre-defined regions-of-interest (ROI) from
    RLum.Data.Image-class, array or matrix objects and provide
    simple image processing capacity. While the function comes with a
    simple control plot output, the results can be passed also to
    plot_ROI()

  • write_R2TIFF(): Export RLum.Data.Image and RLum.Data.Spectrum
    objects or a list of such to TIFF Images. A convenient wrapper
    around the function tiff::writeTIFF()

Bugfixes and changes

merge_RLum.Results()

  • If elements of type matrix, data.frame or vector were merged,
    usually attributes, additional to the standard attributes (e.g.,
    class for data.frame) were lost during the merging. Now, such
    attributes are preserved so far they are not of a similar name as
    the standard object of the object element (e.g., dim for matrix
    or class for data.frame). This small addition allows to merge
    more complex objects and retain all attributes for further
    processing.

plot_DRTResults()

  • The plot messed with the par() settings, which was problematic if,
    for instance, a second x-axis was wanted; fixed.
  • The function examples were not anymore up-to-date; fixed.

plot_RLum.Data.Image()

  • Minor correction of the colour legend, which did always show the
    highest value
  • New ... argument zlim_image to maintain a consistent z-scale
    over a series of images.
  • The colour stretching could fail for lin and a lot of zero values;
    fixed.

plot_RLum.Data.Spectrum()

  • Fixed a bug that let plot_RLum.Data.Spectrum() crash under very
    particular circumstances due to a wrong conditional statement.
  • If the count limits are oddly chosen, i.e. limit_counts is smaller
    than the actual number of counts on the z-scale, the function does
    not crash anymore but replaces the value with the lowest possible
    value.
  • The argument box for the plot persp now accepts alternate for
    the customized plot without the box usually drawn around the plot.
  • The function now returns the adjusted matrix used for the plotting
    regardless of whether the argument plot is set to TRUE or
    FALSE.
  • If the plot type is persp, the default, the “viewing
    transformation matrix” is returned as an attribute pmat. This can
    be further used in conjunction with the function graphics::trans3d
    to add additional information to the graphic.

plot_FilterCombinations()

  • The function returned a wrongly calculated optical density, using
    log() instead of log10; fixed.= Note: The shiny filter app was
    not immediately affected because the values here were taken from a
    spreadsheet.
  • The output object is now invisible since the function’s main purpose
    is to plot a graphic and not return an object.

plot_ROI()

  • Add support for the new function extract_ROI()
  • Add new argument bg_image to support background image plotting
  • The numerical output is now consistently invisble as it is for all
    plot functions in the package
