I have a feeling you didn't type the command yourself, but that you copied and
pasted from the tutorial's web page. You didn't provide the URL of the
tutorial, but I'll bet it was posted on some blog, and that the blog engine
helpfully converted the hyphen in "-R" into an en-dash ("–R") or em-dash
("—R"). They look very similar on-screen, especially in a fixed-width font, but
they're totally different to the Terminal. I'm able to reproduce the error you
experienced if I use an en-dash or em-dash in place of the proper hyphen. So
the lesson is: sometimes it pays to type commands yourself instead of
copy/pasting, just be sure to transcribe them very carefully.
