How can I add Greek letters in R? When I am typing at Greek, doesn't understand the characters, for example I tried to type "κ" which is the Greek "k", but R shows "?". Thanks :)

    Hard to know whether you have the correct locale settings and the associated fonts that should support them. See `?Sys.setlocale` and tell us the results of `Sys.getlocale()` – IRTFM Nov 24 '16 at 16:19
