setCategoricalColorScale {scatterPlotMatrix}

Tells which color scale to use for categorical columns.

Description

Tells which color scale to use for categorical columns.

Usage

setCategoricalColorScale(id, categoricalCsId)

Arguments

id

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

categoricalCsId

One of the available color scale ids (Category10, Accent, Dark2, Paired, Set1).

Value

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

Examples

 if(interactive()) {
   library(shiny)
   library(scatterPlotMatrix)

   ui <- fluidPage(
     selectInput(
       "categoricalCsSelect",
       "Categorical Color Scale:",
       choices = list(
         "Category10" = "Category10", "Accent" = "Accent", "Dark2" = "Dark2",
         "Paired" = "Paired", "Set1" = "Set1"
       ),
       selected = "Category10"
     ),
     p("The selector controls the colors used when reference column is of type categorical"),
     scatterPlotMatrixOutput("spMatrix")
   )

   server <- function(input, output, session) {
     output$spMatrix <- renderScatterPlotMatrix({
       scatterPlotMatrix(iris, zAxisDim = "Species")
     })
     observeEvent(input$categoricalCsSelect, {
       scatterPlotMatrix::setCategoricalColorScale("spMatrix", input$categoricalCsSelect)
     })
