[Rd] capabilities("X11"): Force refresh from within R? (... and minor documentation issue)

Perl6 is not great to do maths, even at basic level. So a dedicated sub-language ("slang" in perl6 linguo) would make a lot of sense indeed, and R would be a natural choice (other possibilities are octave and J). I don't know much about R, I've used it a little bit once but have forgotten pretty
