Making flattened pdfs in Sweave

Question

So I am creating pdfs using Sweave that include some graphs that have a ton of points on them. I can get the pdf well enough, but it seems to have created it with a ton of l

Answer 1

As has already been mentioned you should probably switch to knitr, which makes swapping between pdfs and other formats much nicer. In particular, you should look at:

• the transition guide between knitr and sweave
• global options: that way you can easily swap between pdfs, high-res png and low-res pngs.
• caching: only generate the figures when needed.

Here is an example of using the PNG device:

\documentclass{article}
\begin{document}

<>=
n <- 100000
DF <- data.frame(x=rnorm(n), y=rnorm(n))
plot(DF)
@

\end{document}

There is no need to specify fig=TRUE for knitr. If the image quality of the PNG device in the graphics package is not enough, you can easily switch to other PNG devices, e.g. dev='CairoPNG' or 'Cairo_png'. In Sweave you just write more code to do the same thing.
