Hi Liviu,
Right now our main project is to continue debugging and polishing the
tikzDevice. After that has proceeded, Cameron and I are planning to turn our
attention to Sweave.

Right now, the tikzDevice can be used from within Sweave by following a
process similar to:

...

\begin{figure}

<<"bodFig", echo=F>>=

  tikz( "bodFig.tex" )

  model <- nls ( demand ~ BODu * (1 - exp( -k * Time ) ),
    data=BOD,
    start = list(BODu=5,k=0.1)
  )

  plot( demand ~ Time, data = 'BOD' )

  lines( predict( model ), col='red' )

  dev.off()

@

  \input{bodFig}

  \caption{ BOD data along with least squares regression line. }

\end{figure}

The important differences between a norman Sweave figure are that:

  1. You do not put fig=T in the chunk options.

  2. You must execute tikz() within the figure chunk.

  3. You must execute dev.off() when you are done plotting.

  4. You must \include the figure code that gets produced.

Good luck and thanks for giving the package a try!

-Charlie
