[S]: using symbols with legend

I want to use plotting characters in my legend instead of line types.
In particular, I want to include in my legend the solid square (pch=15)
and the solid circle (pch=16). I originally thought the following would
suffice but it doesn't:

legend(60,14,c("BD Group","BN Group"),pch=c(15,16),bty="n").

Further investigation indicates, as I interpret it, the pch= option
expects a character vector, each element a single character. I want to use
the symbol associated with the numbers 15 and 16.

Any suggestions?
