(For complicated reasons, ) The easiest way to to do this is with something like

xyplot(GCR+GCT ~ FRAC, data=RWF, type=c("g","p"),
       xlab=expression(italic("f")),ylab=expression(italic("S")),
       par.settings = simpleTheme(cex=1.2,pch=c(22,21)),
       auto.key = list(text=c("Targeted Deletion","Random Deletion")))
