iascaggram: Interactive scaggrams

In mbgraphic: Measure Based Graphic Selection

Description

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).

Usage

iascaggram(sdfdata)

Arguments

sdfdata

A list of class "sdfdata".

Details

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.

Value

A shiny app object.

Note

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.
