Examples

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

   ui <- fluidPage(
     fluidRow(
       column(
         2,
         selectInput("zAxisSelect", "Z Axis:", colnames(iris))
       ),
       column(
         2,
         checkboxInput("zAxisUsedCB", "Use Z Axis", FALSE)
       )
     ),
     scatterPlotMatrixOutput("spMatrix")
   )

   server <- function(input, output, session) {
     output$spMatrix <- renderScatterPlotMatrix({
       scatterPlotMatrix(iris)
     })

     observe({
       scatterPlotMatrix::setZAxis(
         "spMatrix",
         if (input$zAxisUsedCB) input$zAxisSelect else NULL
