[R] plot question

[Gabor Grothendieck]

At least on Windows XP R 2.1.1 it does seem like there is quite a 
difference to me, at least when done side by side, which can be 
seen like this:

plot(rnorm(10),rnorm(10),xlab="",ylab="")
title(xlab="x",ylab=quote(bold(3*"4")),font.lab=1,cex.lab=1.25,col.lab="blue")

since the cex.lab will act on both 3 and "4" but bold will only act on
the "4" since numbers such as 3 in the example are ignored by bold.
Maybe in isolation it would suffice.
