An interactive version of the scaggrams from function
scaggram programmed with the package shiny. Selections within the scaggram can be made by clicking or brushing. A selection implies drawing the corresponding scatterplot(s).
A list of class
Reordering is done with the functions
sdf_sort (options 'Use all scagnostics' and 'Use only chosen scagnostics') or
sdf_quicksort (option 'Quick'). The glyphs drawn by choosing option 'add -> glyphs' represent all given scagnostics.
A shiny app object.
The scagnostics need to lie between 0 and 1.
sdf_sort can be very slow for data sets with a huge number of variables. Use Option 'Quick' in this case for a fast reordering or use
sdf_sort (with a time limit if necessary) before starting the interactive app.
Adding scatterplots or glyphs is only advisable for a small number of variables.
