scatterPlotMatrix (version 0.3.0)

setCategoricalColorScale: Categorical color scale

Description

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

Usage

setCategoricalColorScale(id, categoricalCsId)

Value

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

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).

Examples

 if(interactive() && require(shiny)) {
   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("Selector controls used colors 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)
     })
   }

   shinyApp(ui, server)
