Unable to use fa icons

[Brian_Carey]

Hi,

I'm working my way through the R Shiny Articles and am in the section on gadgets. When working with the tabs.R file I get the following error:

The `name` provided ('map-o') does not correspond to a known icon

In fact I can't seem to reference any fa name. I explicitly loaded the library even though it's not shown in the Article's example to no avail. This is the first time I use fa icons with R (I've used them a lot in js and python).

I'd appreciate any help. Loving the articles!

For reference this is from the website:

library(shiny)
library(miniUI)
library(leaflet)
library(ggplot2)

ui <- miniPage(
  gadgetTitleBar("Shiny gadget example"),
  miniTabstripPanel(
    miniTabPanel("Parameters", icon = icon("sliders"),
      miniContentPanel(
        sliderInput("year", "Year", 1978, 2010, c(2000, 2010), sep = "")
      )
    ),
    miniTabPanel("Visualize", icon = icon("area-chart"),
      miniContentPanel(
        plotOutput("cars", height = "100%")
      )
    ),
    miniTabPanel("Map", icon = icon("map-o"),
      miniContentPanel(padding = 0,
        leafletOutput("map", height = "100%")
      ),
      miniButtonBlock(
        actionButton("resetMap", "Reset")
      )
    ),
    miniTabPanel("Data", icon = icon("table"),
      miniContentPanel(
        DT::dataTableOutput("table")
      )
    )
  )
)

server <- function(input, output, session) {
  output$cars <- renderPlot({
    require(ggplot2)
    ggplot(cars, aes(speed, dist)) + geom_point()
  })

  output$map <- renderLeaflet({
    force(input$resetMap)

    leaflet(quakes, height = "100%") %>% addTiles() %>%
      addMarkers(lng = ~long, lat = ~lat)
  })

  output$table <- DT::renderDataTable({
    diamonds
  })

  observeEvent(input$done, {
    stopApp(TRUE)
  })
}

runGadget(shinyApp(ui, server), viewer = paneViewer())

instead of "map-o" try just "map"
