[R] Is there a plotmath symbol \mapsto?

The only symbols plotmath has access to are those in the Adobe Symbol 
encoding.  You can display all of those using the example at the bottom 
of ?points, as ?plotmath did tell you.  (So it was a rather rich asking 
for an example.)

It also tells you that on some devices/platforms you can use Unicode 

Now TeX (not LaTeX) does not define exactly which glyph \mapsto should 
output, but Unicode \u21A6 is often called 'mapsto' (how Unicode glyphs 
are rendered is font-specific, of course).  That works for me with 
cairo-based devices on Linux; however on my Mac that glyph is not in the 
standard fonts for Quartz-based devices.
