Have a look at the help in text(), i.e.

help(text)

I think you are looking for something along the lines of:

xyplot(power1+power2 ~ pi0, data=resultb, ylab="Average Power", type="l", pch=LETTERS[1:2], lty=c(1:2), main="(a)", xlab=expression(pi[0]))

i.e. i am assuming you want pi subscript zero. An example of using text would be

text(6,10,expression( y==1.5*x+10))

HTH,
Jeremy

Views expressed above, no matter how badly spelt, are my own... I think?
