There is a new version of pgfSweave, and its awesome!

I just uploaded version 1.2.1 of pgfSweave, and I think it is just great! The most notable new feature is the use of the TikZ externalization library list and make feature instead of the pgf \begingraphicnamed functionality. This has some important consequences:

  1. PGF 2.10 is required! This has been out for some months now but many LaTeX distros are notoriously slow at updating, so you may need to update manually.
  2. Backward compatibility may break with some documents who still have the \pgfrealjobname hardcoded or who use the tex.driver option.
  3. A new workflow is required to compile documents (it includes make), this is outlined in the vignette.
  4. You can use all the nifty features in the TikZ externalization library, see the TikZ/PGF manual for more details.
  5. Most importantly it is faster!

There are a boat load of other changes and new features, I think you like it, check them out:

————————–
Version 1.2.1 – 2011-04-03
————————–
* [NEW] If PGF 2.10 is not available, issue a startup message but still
        load the package (So the package can go on CRAN). PGF 2.10
        is still required to compile .tex file produced with pgfSweave
* [NEW] Remove null device code which could cause problems with grid
        graphics
* [NEW] Example using xelatex for external graphics
* [NEW] Chunk options `relwidth’ and `relheight’ for scaling figures
        relative to the `width’ and `height’ options (thanks to Fabrice
        Rossi for the patch)
* [CHANGED] Fix the internal caching of external graphics, it now works as
        expected and can save significant time

————————–
Version 1.2.0 – 2011-02-21
————————–
* [NEW] Use the tikz externalization library instead of the pgf backend.
        This allows for more flexibility and faster compilations but
        BEWARE, this requires at least pgf 2.10 and may break backward
        computability in some cases
* [NEW] GNU Make is now a system requirement for externalizing graphics,
        NOT for compiling the package
* [NEW] Option to specify number of processors when externalizing graphics
* [NEW] Externalized graphics now have another layer of crude caching
* [NEW] Highlighted output is now output in a separate environment to fix
        the centering issues
* [NEW] Example document using plain latex and the tikz external library
        to generate eps graphics,
        `inst/example/pgfSweave-latex-example.Rnw`
* [CHANGED] The command line interface is now much simpler internally
        and uses optparse instead of getopt for more flexibility (the
        optparse package is now a dependency)
* [CHANGED] The `tex.driver’ option has been removed, the same effect can
        be achieved using the tikz externalization library, see the new
        example for how
* [DEPRECIATED] The `pgf’ option is depreciated, please use the `tikz’
        option

  1. One very specific use that this feature was created for (there may be others) was for code chunks that are reused in a both an article and in a beamer document. That way the writer can re-use chunks with the rel{height,width} options and only change the width and height in \SweaveOpts{}.

  2. Having mondo problems getting pgfSweave to run in LyX on Ubuntu 10.04.

    http://stackoverflow.com/questions/7354222/sweave-lyx-fig-t-in-sweave

    Removed Ubuntu’s texlive-full because apparently that doesn’t work

    Upgraded to a newer version of LyX (2.0.1) than currently supported in Ubuntu

    Still getting really cryptic errors in LyX:

    An error occurred while running: Rscript ‘/home/mars/.lyx/scripts/lyx-sweave-exec.R’ ‘UTF-8′ ‘pgfSweave’ "/home/mars/" "/tmp/lyx_tmpdir.T1663/lyx_tmpbuf2/" "test.sweave.lyx.Rnw" > "test.sweave.Rnw".log 2>&1

    Not that I expect your help — I’m just leaving this info here as a warning to others who might be trying to embark on the Sweave journey to “time savings”.

  3. Sorry but I will be of no help here, I have never actually tried to use LyX with pgfSweave.

    Your best bet would be to ask Yihui (he has commented above) as he got the two hooked up in the first place.

    Thanks for your interest!
