[Rd] Typo in R Help INSTALL {utils} (PR#14045)

[Prof Brian Ripley]

The source file reads

   Use \command{R CMD INSTALL --help} for concise usage information,

so I see no 'typo'.

The issue is apparently in the rendering of -- as - in \command.  I 
am presuming you are viewing HTML in the Mac GUI, but can you please 
confirm exactly what you are looking at.

I suspect from the ? I see (twice) in your message that you are 
seeing an endash and not a single hyphen.  That's what HTML help on 
Linux is showing as for me.
