#Rstats life-changing but abominable hack of the day: system2("open", ".") (Replace xdg-open for open if you're on Linux instead of a Mac. This is more useful to the Vim + REPL set than RStudio users. Not guaranteed to actually change your life.) Edit: thanks @bastistician for pointing out that browseURL(".") does the same thing (and probably works on Windows—IDK and fortunately have no way to check).
