setRegressionType(id, regressionType)

Value

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

id

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

regressionType

Binary code indicating the type of regression plot (bit 1: linear, bit 2: loess).

Examples

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

   ui <- fluidPage(
     checkboxInput("linearRegressionCB", "Linear Regression", FALSE),
     checkboxInput("loessCB", "Local Polynomial Regression", FALSE),
     p("The chech boxes controls type of regression to use for regression plots"),
     scatterPlotMatrixOutput("spMatrix")
   )

   server <- function(input, output, session) {
     output$spMatrix <- renderScatterPlotMatrix({
       scatterPlotMatrix(iris)
     })
     observe({
       linearFlag <- ifelse(input$linearRegressionCB, 1, 0)
       loessFlag <- ifelse(input$loessCB, 2, 0)
       scatterPlotMatrix::setRegressionType("spMatrix", linearFlag + loessFlag)
     })
   }
