Hi Marc
I forgot about the other things than atop in my reply. Others seem to have
exhausted base graphics options
Could using grid.text solve your problems ?
e.g. Guide code
plot(1,1)
grid.clip()
vp <- viewport(width = 1, height = 1)
pushViewport(vp)
grid.text( "text", 0.25,0.25)
popViewport(0)
Regards
Duncan

Subject: Re: [R] \n and italic() in legend()
Hi,
Thanks a lot to Duncan Mackay for the trick using atop() [but the
legends are centered and not left aligned] and also for the suggestion
of William Michels to use simply ",". However this last solution
prevents to use several legends.
Here is a solution to allow both return within a legend and several legends:
plot(1, 1)
v1 <- c(expression(italic("p")*"-value"), expression("based on
"*italic("t")*"-test"))
v2 <- c(expression(italic("w")*"-value for A"), expression("and B
identical models"))
legend("topright", legend=c(v1, v2), lty=c(1, 0, 1, 0), y.intersp = 1,
bty="n", col=c("black", "", "red", ""))
Thanks again
Marc
