Yes, this makes sense.  Though, since really all I need to do is wrap
source code written in R in a \LaTeX environment, I might also like to
use

#v+
#+LATEX:  \begin{Scode}
a <- 3
a
#+LATEX:  \end{Scode}
#v-

While I think opening up this list to customization is probably a good
idea, I could not get my new entries to behave the way I wanted.  The
problem, I suspect, may have to do with the ordering of the different
language environments.  Suppose I had

#v+
#+BEGIN_LATEX
\begin{Scode}
a <- 3
a
\end{Scode}
#+END_LATEX
#v-

in an org file.  I guess that I want the code within the Scode
environment to me in r-mode, and the code outside of that but still
within the LATEX block to be in LaTeX-mode.  In what order should these
two definitions appear within the re-list?

FWIW, attached is a patch of the setup I tried to use.  When I hit C-c '
inside either of the above examples, I get a temporary buffer that's in
latex-mode.  I was hoping to get a temporary buffer in r-mode.  I also
tried a version of the code that used the same entries in the re-list,
but put them at the bottom, under the entries for ascii.  Same results.

Thanks for any further advice,
