Reactive Function Parameters

Question

My goal is to make a reactive shiny function in R. There are multiple outputs (e.g. tables) which can be bind to a similar function. However I need the function to react on some

Answer 1

This should work instead:

getData <- eventReactive(input$funParameter, {
  corrStartDate <- input$StartDate
  corrEndDate <- input$EndDate

  return(someData(corrStartDate, corrEndDate, input$funParameter))
})

eventReactive only updates if arguments stated up front change. Practically speaking, this reactive will not trigger if input$StartDate or input$EndDate changes.

If this is not what you want, normal reactive functions should work. I.e.:

getData <- reactive({

  funParameter <- input$funParameter
  corrStartDate <- input$StartDate
  corrEndDate <- input$EndDate

  return(someData(corrStartDate, corrEndDate, funParameter))
})

which will trigger if any of the inputs change
