scatterPlotMatrix (version 0.3.0)

setContinuousColorScale: Continuous color scale

Description

Tells which color scale to use when the Z axis is set to a continuous column.

Usage

setContinuousColorScale(id, continuousCsId)

Value

No return value, called from shiny applications for side effects.

Arguments

id

Output variable to read from (id which references the requested plot).

continuousCsId

One of the available color scale ids (Viridis, Inferno, Magma, Plasma, Warm, Cool, Rainbow, CubehelixDefault, Blues, Greens, Greys, Oranges, Purples, Reds, BuGn, BuPu, GnBu, OrRd, PuBuGn, PuBu, PuRd, RdBu, RdPu, YlGnBu, YlGn, YlOrBr, YlOrRd).

   library(shiny)
   library(scatterPlotMatrix)

   ui <- fluidPage(
