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:
- 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.
- Backward compatibility may break with some documents who still have the
\pgfrealjobnamehardcoded or who use the
- A new workflow is required to compile documents (it includes make), this is outlined in the vignette.
- You can use all the nifty features in the TikZ externalization library, see the TikZ/PGF manual for more details.
- 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
* [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,
* [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’
