  sidebarPanel( 
    sliderInput("num", "Number:",min = 0, max = 5,step=1,value=c(1,2))),
  mainPanel(plotOutput("plot2")))

server <- function(input,output){

  dat <- reactive({
    test <- df[df$num %in% seq(from=min(input$num),to=max(input$num),by=1),]
    print(test)
    test
  })

  output$plot2<-renderPlot({
    ggplot(dat(),aes(x=date,y=num))+geom_point(colour='red')},height = 400,width = 600)}
shinyApp(ui, server)
