[R] \n and italic() in legend()

[William Michels]

Hi Marc,

I can't seem to get "\n" to work,  but simply using c() and "y.intersp
= 1" looks fine:

> plot(1, 1)
> v1 <- c(expression(italic("p")*"-value"), expression("based on "*italic("t")*"-test"))
> legend("topright", legend=v1, y.intersp = 1, bty="n")



Hope this helps,

Bill
