Those are not in the Adobe Symbol encoding used for plotmath.

Since you have not told us your platform and locale as requested in the 
posting guide, I don't know if the following is relevant to you.

If you have a suitable Unicode font and the means to use it (which most 
likely means a UTF-8 locale in R < 2.7.0) they are the glyphs for
"\u226a"
and "\u226b" (see 
http://www.alanwood.net/unicode/mathematical_operators.html).  A quick 
check suggests that not many fonts do.
