'Font Awesome' Icons as 'shiny' 'favicons'.
favawesome 
Easily use {fontawesome} icons as shiny favicons (the icons that appear on browser tabs). Font Awesome is a popular set of icons that can be used in web pages. {favawesome} provides a simple way to use these icons as favicons in shiny applications and other HTML pages.
Installation
You can install the latest release of favawesome from CRAN with:
install.packages("favawesome")
You can install the development version of favawesome from GitHub with:
# install.packages("pak")
pak::pak("shinyworks/favawesome")
Motivation
If you’ve spent time in the Chrome Developer Tools Console (ctrl + shift + I) for shiny apps, you may have seen this familiar error message:

False alarms make it easy to miss real error messages, so I wanted a way to silence that error message without adding a bunch of dependencies to my shiny app. This package does not add any dependencies that are not already required by {shiny}.
Usage
Add a call to favawesome::fav()
to your shiny UI code or other HTML.
html_page <- htmltools::tags$html(
favawesome::fav("earth-africa", fill = "blue"),
htmltools::tags$body(
htmltools::tags$h1("Hello world!"),
htmltools::tags$p("(on the browser tab)")
)
)
htmltools::html_print(html_page, viewer = utils::browseURL)
