The fontawesome R package makes it very easy to insert Font Awesome icons into R Markdown documents and Shiny apps (or, anywhere else you need to put them).

Examples

The fa() function can be used to insert an FA icon. For example, we can get the r-project icon in steelblue:

fa(name = "r-project", fill = "steelblue")
#> <svg xmlns="http://www.w3.org/2000/svg" viewBox="0 0 581 512" class="rfa" style="height:0.75em;fill:steelblue;position:relative;"><path d="M581 226.6C581 119.1 450.9 32 290.5 32S0 119.1 0 226.6C0 322.4 103.3 402 239.4 418.1V480h99.1v-61.5c24.3-2.7 47.6-7.4 69.4-13.9L448 480h112l-67.4-113.7c54.5-35.4 88.4-84.9 88.4-139.7zm-466.8 14.5c0-73.5 98.9-133 220.8-133s211.9 40.7 211.9 133c0 50.1-26.5 85-70.3 106.4-2.4-1.6-4.7-2.9-6.4-3.7-10.2-5.2-27.8-10.5-27.8-10.5s86.6-6.4 86.6-92.7-90.6-87.9-90.6-87.9h-199V361c-74.1-21.5-125.2-67.1-125.2-119.9zm225.1 38.3v-55.6c57.8 0 87.8-6.8 87.8 27.3 0 36.5-38.2 28.3-87.8 28.3zm-.9 72.5H365c10.8 0 18.9 11.7 24 19.2-16.1 1.9-33 2.8-50.6 2.9v-22.1z"/></svg>

As can be seen, what we really get from the function is an SVG object that represents the icon. This can be directly used within R Markdown with:

{text} `r fa(...)` {text}

Font Awesome SVG icons are great to use instead of <i> tags + font files for a few reasons:

R Markdown

Here is an example R Markdown document that includes Font Awesome icons:

---
title: "Font Awesome in R Markdown"
output: html_document
---

```{r load_packages, message=FALSE, warning=FALSE, include=FALSE} 
library(fontawesome)
```

# Just a few tests with `r fa("font-awesome-logo-full", fill = "forestgreen")`

It works well in headings...

# `r fa("r-project", fill = "steelblue")` H1 Heading

## `r fa("r-project", fill = "steelblue")` H2 Heading

### `r fa("r-project", fill = "steelblue")` H3 Heading

#### `r fa("r-project", fill = "steelblue")` H4 Heading

##### `r fa("r-project", fill = "steelblue")` H5 Heading

...and works equally well within inline text: `r fa("r-project", fill = "steelblue")`.

This will appear, when knit, as:

Shiny

Here’s a Shiny app (from the Shiny Gallery) that’s been slightly modified to incorporate Font Awesome icons in the text above the three search fields:

library(shiny)
library(DT)
library(ggplot2)
library(fontawesome)

ui <- fluidPage(

  titlePanel("Basic DataTable"),

  # Create a new Row in the UI for selectInputs
  fluidRow(

    column(
      width = 4,
      selectInput(
        inputId = "man",
        label = tags$p(fa("car", fill = "purple"), "Manufacturer:"),
        choices = c(
          "All",
          unique(as.character(mpg$manufacturer))))
    ),

    column(
      width = 4,
      selectInput(
        inputId = "trans",
        label = tags$p(fa("car", fill = "forestgreen"), "Transmission:"),
        choices = c(
          "All",
          unique(as.character(mpg$trans))))
    ),

    column(
      width = 4,
      selectInput(
        inputId = "cyl",
        label = tags$p(fa("car", fill = "steelblue"), "Cylinders:"),
        choices = c(
          "All",
          unique(as.character(mpg$cyl))))
    )
  ),

  # Create a new row for the table.
  fluidRow(
    dataTableOutput("table")
  )
)

server <- function(input, output) {

  # Filter data based on selections
  output$table <- renderDataTable({

    data <- mpg
    if (input$man != "All") {
      data <- data[data$manufacturer == input$man,]
    }
    if (input$cyl != "All") {
      data <- data[data$cyl == input$cyl,]
    }
    if (input$trans != "All") {
      data <- data[data$trans == input$trans,]
    }
    data
  })
}

shinyApp(ui = ui, server = server)

The Shiny app will look something like this:

Please note that using shiny::icon() in place of fontawesome::fa() will still work. Internally, the icon() function will call fontawesome's fa_i() function, which generates an old-school <i> tag for the icon.

Installation

Want to try this out? The fontawesome package can be installed from CRAN:

install.packages("fontawesome")

Also, you can install the development version of fontawesome from GitHub:

devtools::install_github("rstudio/fontawesome")

If you encounter a bug, have usage questions, or want to share ideas to make this package better, feel free to file an issue.
