R help - Jan 2013 - italic font for legend text when using expression function for symbols

Hello,

I'm trying to add a symbol (Delta) to plot legend with text using
"expression(paste())" but this disables the text.font that allows to
use
bold or italic text.
as follows:
x=c(1:10)
y=c(1:10)
plot(x,y)
legend(1,10,legend=c("A","B","C",expression(paste(Delta,
D))),
       pch=c(24,18,17,16),cex=2,text.font=3,bty="n")

Any suggestion to how I can add the Delta symbol and have a italic font?

Thanks

plot(1)
legend('topleft',legend=expression(A,italic(A),bolditalic(A),Delta*italic(D)))
