[R] Baffled: triggering error message with an sd result in odfWeave?

[Sarah Goslee]

Nothing leaps out as obviously wrong to me. It may even be something earlier
in the ODFWeave file that is causing the error. You said the code works at
the command line, right?

The next thing I'd do is try to make the smallest possible ODFWeave file
that has the problem - make a copy, then start deleting bits until it works.
If  possible, try with a different dataframe as well (rename something else
to trainwhateveritwas), or generate a new random dataframe from within
your ODFWeave document.
