Use R help system with Vimium

I use R help in browser for

• Vim keybindings with Vimium, particularly useful for
  • navigate up/down
  • navigate forward/backward page
  • open multiple links
  • search
  • hyperlinks
  • etc
• I prefer reading documentation on white background
• Style page with custom CSS (see below) with Stylebot
• Type e.g. ?grepl in R REPL to fire up the browser
• Quite often, when reading R docs, quite often I need to browser other stuffs, for example, StackOverflow, etc.

Have been using this setup for a while. I am enjoying it so far.

My Setup

.Rprofile

options(
    # Disable VSCode's built-in help system. See [VSCode-R](https://github.com/Ikuyadeu/vscode-R)
    vsc.helpPanel = FALSE,

    browser = function(url) {
      # Customize my_browser. Use browser app mode to hide url bar.
      system2('my_browser', url, stdout = FALSE, stderr = FALSE)
      # e.g. Chrome on Linux
      # system2('google-chrome-stable', ...)
      # e.g. Chrome on Windows
      # system2('chrome.exe', ...)
    })

Style page with custom CSS (see below) with Stylebot

Set custom site with wildcard e.g. */library/, */doc
