yes, that should work. Try to export the following several times. The
first number should not change.
(note: maybe you'd have to execute the inner_test_cached once on your
system)
#+name: inner_test_cached
#+begin_src R :cache yes :exports none
rnorm(1)
#+end_src
#+results[dbeb7280be41fdc949815808cf601a6d01a400bb]: inner_test_cached
: 1.12399967834262
#+name: inner_test_not_cached
#+begin_src R :exports none
rnorm(1)
#+end_src
#+results: inner_test_not_cached
: -0.562660468468834
#+name: test
#+begin_src latex :noweb yes
\begin{equation}
<<inner_test_cached()>>
!=
<<inner_test_not_cached()>>
\end{equation}
#+end_src
Cheers,
Andreas
