Hide/show outputs Shiny R

Question

I am trying to find out how to show and hide my outputs like graphics and tabels each time when the user change something in the widjets. For instance I have a slider input

Answer 1

The reason your code didn't work is because you didn't make a call to useShinyjs() (if you read the documentation or look at any examples of using shinyjs, you'll see that you HAVE to call useShinyjs() in the UI).

I couldn't replicate your code because it had too many errors, but just to demonstrate that it does work with outputs, here's a small example you can run. In your project, just add shinyjs::useShinyjs() somewhere in the UI.

library(shiny)
library(shinyjs)

ui <- fluidPage(
  useShinyjs(),
  actionButton("hideshow", "Hide/show plot"),
  plotOutput("plot")
)

server <- function(input, output, session) {
  output$plot <- renderPlot({
    plot(rnorm(100))
  })

  observeEvent(input$hideshow, {
    # every time the button is pressed, alternate between hiding and showing the plot
    toggle("plot")
  })
}

shinyApp(ui = ui, server = server)
