In rstudio/reportsWS: Interactive Reports with R Markdown and Shiny Workshop

eventReactive() provides a useful way to delay reactions when combined with an actionButton().

selectInput("iriscol", label = "Select a variable", choices = names(iris))

actionButton("go", "Go!")

data <- eventReactive(input$go, { iris[[input$iriscol]] })

renderPlot({
  hist(data(), probability = TRUE)
})
