I find that I need to do:
Recalling the variable $a$ set above: $a = \Sexpr{a}$.

in order to get the Sweave example to work. That is, I need to include the backslash prefix to \Sexpr. While this is probably obvious to most, I am only just starting to learn LateX and so it is easy to get tripped up.
Cheers
Mark

Poore Wed, 23 Jan 2013 03:07:27 +0000 http://www.johndcook.com/blog/?p=12623#comment-3924 You might be interested in my PythonTeX package for LaTeX. It is similar to Pweave, but the document you write is actually a valid .tex document, so editing and compiling can be a bit more convenient. PythonTeX saves or caches all output, allows user-defined sessions that automatically run in parallel, synchronizes error line numbers with the .tex document, and can be set to automatically check for modified external dependencies such as data files. It also provides syntax highlighting of typeset code via Pygments.

It should be straightforward to add a Pweave export capability.

It isn’t actively maintained at present, but still provides a great tool for quick projects.

John’s distinction about which angle you are coming to technical documentation from is a good one though, and the next time I am writing a longer report with some code, I’ll remember Pweave.

If you’re coming from the code end and want to add documentation, IPython is the way to go. But if you’re coming from the document end, wanting to make a document a little more dynamic, Pweave may be preferable.

I ran into this when I wrote up a LaTeX report the other day that contained a few simple calculations. I had to change some data, and I changed most of the computed values that needed to change as a result, but missed some. Then I wished I’d used Pweave.

Markdown is so much nicer to work with day-to-day than LaTeX.

Small remark: you left a “Calling R inline” in the Pweave part.
