[R] Title with substitute and paste

Interesting ...

I believe that the problem is when you use the substitute construction, you
produce an expression object that is interpreted and rendered using the fonts via
the plotmath facility (?plotmath).

When you just use paste, the title is character and gets rendered via the
defaults of title.

You can make them the same by making them both character strings, e.g., vis

> nval <- 20
> plot(0,0)
> title(paste("n = ", nval))

for example.

Or you could wrap the text version in expression() to use plotmath fonts.
