Seems to work on a few test cases.

I'd move the strings to defconsts.

Putting a newline before each `%S' will outdent the first line of 
:var value when it is echoed in the session log so it will be easier to 
view.

With Eric's input on this:

Would you also change this at the end of org-babel-R-assign-elisp:

                         res})" name file header row-names max))))
-    (format "%s <- %s" name (org-babel-R-quote-tsv-field value))))
+    (format "%s <- %S" name
+	    (if (stringp value) value (prin1-to-string value)))))

??

I think this is innocuous for plain strings with no internal quotes, but 
allows almost anything to be passed to R as a string.

So
 	:var x=[1 2 3 "4" 5]

will be passed to R as x <- "[1 2 3 \"4\" 5]"

instead of x <- "[1 2 3 "4" 5] which throws an error.

And this just works:

#+NAME: latex-capt
#+BEGIN_SRC latex
   \begin{math}
     y = X\beta,
     \mbox{where } \beta = %beta%
   \end{math}
#+END_SRC

#+BEGIN_SRC R :var ytxt=latex-capt :results raw :wrap latex
beta <- 1.234
sub("%beta%",beta,ytxt)
#+END_SRC


HTH,

Chuck
