r - Shiny renderPlotly with two conditions -


i developing app in shiny. want render plot using submit button. want print labels if user check inputcheckbox. able render plot via button. doesnt work when checkbox checked.

here code:

 library(shiny)  library(plotly)   ui <-  fluidpage(  actionbutton('run', 'run'),  checkboxinput('printlab', 'label', false),  plotlyoutput("plot1")  )   server = function(input, output) {  output$plot1 <- renderplotly({  req(input$run)  isolate({    ggplotly(ggplot(data = mtcars, aes(wt, hp)) +             geom_point(size=1, colour = "grey"))    })    req(input$printlab)   isolate({    ggplotly(ggplot(data = mtcars, aes(wt, hp)) +             geom_point(size=1, colour = "grey") +            geom_text(aes(label=wt), size=3, colour = "black"))    })   }) }   runapp(shinyapp(ui, server))

i'm no shiny expert, req(input$printlab) doesn't right me. accomplish going for?

server <- function(input, output) {   output$plot1 <- renderplotly({     req(input$run)      if (!input$printlab) {       ggplotly(ggplot(data = mtcars, aes(wt, hp)) +               geom_point(size=1, colour = "grey"))     } else {       ggplotly(ggplot(data = mtcars, aes(wt, hp)) +               geom_point(size=1, colour = "grey") +              geom_text(aes(label=wt), size=3, colour = "black"))     }    }) }

(i'm sure there's better way. that's off top of head.)
