哑铃字形不适用于闪亮的仪表板

Question

Though plenty of glyphicons work, the dumbell is not one of them. Any ideas?

server.r

library(shinydashboard)
shinyServer(function(input, output) {})

ui.r

dashboardPage(
      title = "O8 Trainer",
      dashboardHeader(
        title = "Train!"
      ),
      dashboardSidebar(
        sidebarMenu(
          menuItem("Trainer", 
          tabName = "trainTab", 
          icon = icon("dumbbell", lib = "glyphicon")) #"cog" works here, for instance.
        )
      )
    )

Answer 1

Original answer: the dumbbell icon is not available from the free iconset

The comments below are correct: using icon() is shiny only gives you access to whatever glyphicons are made available through bootstrap as per http://getbootstrap.com/components/#glyphicons

Answer 2

Most answers link to the getbootstrap.com components page (including the icon vignette), but it is not clear where the list is on that page. The icons list on getbootstrap.com mostly contains icons that will not work with Shiny. Instead, I use this list and they all work well.

On that page only include the tail of the name of the icon. For instance, for icon name "glyphicon glyphicon-music", proper shiny code is:

icon("music", lib = "glyphicon")
