[R] greek letters in "italic" font

[Gabor Grothendieck]

You could piece it together using the Hershey fonts for the italic rho:

op <- par(xpd = NA)
plot(1, type = "n", ylab = "")
u <- par("usr")
text(u[1] - .1 * diff(u[1:2]), 1, "\\*r", vfont = c("serif", "italic"))
par(op)

Now add the rest.
?Hershey
?par
?strwidth
