RLumShiny 0.2.0 (Release date: 2017-06-26)

• Major overhaul of the data input panel for most applications. Uploaded text files are now imported via ‘data.table::fread()’, which automatically detects the delimiter and potential headers. Hence, all widgets related to data import are no longer required and were removed (#14).

• The input data can now be directly manipulated in the newly added spreadsheet(s) in the data input panels. The spreadsheets also allow copy and pasting of data, so uploading a file is no longer the only way to provide user data (#12).

• New Dashboard addin added. The dashboard provides access to all available applications in the package and can be accessed either (i) through the addin dropdown menu in the RStudio IDE or (ii) by running ‘app_RLum()’ without any keyword.

• Implemented newest shiny feature (v0.14) to bookmark the current app state. All apps now include a bookmark button, which returns a URL query string that can be used to restore the app’s state at any later time.

• New application to plot filter combinations along with the optional net transmission. Base function: Luminescence::plot_FilterCombinations(). Keyword for app_RLum(): ‘filter’. External contribution by Urs Tilmann Wolpert (Justus-Liebig-University Giessen) and Sebastian Kreutzer (Universite Bordeaux Montaigne).

  • the plot now also shows the CW-OSL data curve
