  envir = parent.frame()
)

# NOT RUN {
if (interactive()) {
  library(shiny)
  library(rhandsontable)

  ui <- fluidPage(
    dataInputUI("input1"),
    rHandsontableOutput("data1")
  )

  server <- function(input,
                     output,
                     session) {
    data_input1 <- dataInputServer("input1")

    output$data1 <- renderRHandsontable({
      if (!is.null(data_input1())) {
        rhandsontable(data_input1())
      }
    })
  }

  shinyApp(ui, server)
}
