Hi e-letter,
You can use escape codes in a string to insert symbols in an axis label 
like this:

plot(...,xlab="Male\u2642")

if you are in a Unicode locale. You will have to find out which escape 
codes work in your locale, if the symbols you wish to use exist in that 
locale and what their escape codes are.
