Catherine 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 On Friday 18 January 2008 10:16:22 pm cathelf wrote: > Hi, > Sorry for bothering you again.

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