'plots'?  On what OS and what device?   (There is no general solution 
here.)

That symbol is in neither of the Latin-1 nor symbol encoding used in R's 
standard fonts for postscript(), pdf() and the like.  Since it is not in 
the Adobe symbol encoding it is not accessible via plotmath.

It is Unicode character U+2113, and so on UTF-8 R systems you may well be 
able to enter it as \u2113 and get it plotted on-screen in a suitable 
font.  But we'd need to know a lot more about your system to advise on how 
exactly to do so.
