group_selectors(input, output, session, verif_data)

Arguments

id	An ID string for the module's UI
input	input reactive
output	output reactive
session	Session from which to make a child scope (the default should almost always be used).

Value

Examples

library(shiny)

ui <- fluidPage(
  fluidRow(
    group_selectorsUI("grps")
  ),
  fluidRow(
    plotOutput("plt")
  )
)

server <- function(input, output, session) {
  grp_data <- callModule(group_selectors, "grps", reactive(verif_data_grp))
  output$plt <- renderPlot({
    plot_point_verif(req(grp_data()), spread)
  })
}
