Riemann integrable functions
How do you do the capital script R for Riemann integrable functions? It looks like the same "font" as $\displaystyle \ell$ but it is a capital R.

Chop Suey
This perhaps?
$\displaystyle \mathfrak{R}$

$\displaystyle \mathcal{R}$ ?

Can you draw it or describe it more precisely ? I've never heard of such an R (Doh)
And maybe it would be quicker to write "Riemann integrable" :D

It is the script font \mathscr{R} (but we don't seem to have it implemented)

$\displaystyle \mathscr{R}$

I got it from Rudin...and I wanted it because it was pretty (Happy)...and as CB pointed out it is the \mathscr font...you can see some examples of it here http://www.ctan.org/tex-archive/info...symbols-a4.pdf on page 65
