add_busy_spinner() for shinydashbaord

[kueckelj]

Hey, I'm using shinydashboard and I'd like to integrate a busy spinner in the top right corner - as you've shown in one of your examples. Would you mind sharing the code of your example where you add a busy_spinner to shinydashboard - so I know where to put the function in order to make it work? I don't know why but wherever I place the function I get an error message including " Expected an object with class 'shiny.tag'. "!

That'd be great!

Greetings

Hello Jan!

Ah yes I should include this example somewhere! You probably put add_busy_spinner in dashboardHeader ? You should use it in sidebar or body. Here's an example :

library(shiny)
library(shinybusy)
library(shinydashboard)

ui <- dashboardPage(
  dashboardHeader(title = "Iris clustering"),
  dashboardSidebar(),
  dashboardBody(

    add_busy_spinner(spin = "cube-grid", margins = c(0, 10), color = "#FFF"),

    headerPanel('Iris k-means clustering'),

    sidebarLayout(
      sidebarPanel(
        selectInput('xcol', 'X Variable', names(iris)),
        selectInput('ycol', 'Y Variable', names(iris),
                    selected=names(iris)[[2]]),
        numericInput('clusters', 'Cluster count', 3,
                     min = 1, max = 9),
        actionButton("sleep", "Sleeeep")
      ),
      mainPanel(
        plotOutput('plot1')
      )
    )
  ),
  title = "Dashboard example"
)

server <- function(input, output, session) {

  # Combine the selected variables into a new data frame
  selectedData <- reactive({
    iris[, c(input$xcol, input$ycol)]
  })

  clusters <- reactive({
    kmeans(selectedData(), input$clusters)
  })

  output$plot1 <- renderPlot({
    palette(c("#E41A1C", "#377EB8", "#4DAF4A", "#984EA3",
              "#FF7F00", "#FFFF33", "#A65628", "#F781BF", "#999999"))

    par(mar = c(5.1, 4.1, 0, 1))
    plot(selectedData(),
         col = clusters()$cluster,
         pch = 20, cex = 3)
    points(clusters()$centers, pch = 4, cex = 4, lwd = 4)
  })

  observeEvent(input$sleep, {
    Sys.sleep(5)
  })

}

shinyApp(ui, server)

Exactly. As the vignette said “somewhere in your UI” I just tried a few random positions in the sidebar and the header but none of them worked. But yours – which was literally the only one I hadn’t tried, stupidme 😃 - does!! Thank you very much for the quick response!
