I want to make my R Shiny App multilingual, but I don't know, where to start from. Is there any libraries or Shiny widgets for switching the language in the Shiny App?
More generally, what are the best practices for internationalization in R? Is there any tutorials? I know, there is a gettext command, which comes from GNU gettext, but I'm not very handy with it. Should I read GNU gettext manual first (and what chapters will be enough for beginner)?
