You don't just need a viewer, you need a help compiler.  We were 
unable to find a complete one other than from Microsoft, and the 
latter seems no longer to be under development (and has a serious 
security alert on it).  So the future of CHM help even for R under 
Windows is uncertain.

There is for R for Windows, it that is what you are asking.  And you 
can run Windows R under WINE.

Personally, I like the Mac OS X compiled help system better than the 
Windows one, but we do not provide that even on Mac OS X.  And these 
things *are* a matter of personal preference.
