Like many ggplot articles, they seem to consider the primary output being the Web, and not print publications.

One thing I haven't quite figured out with ggplot2 is how to keep the text size constant in publications across figures. If you look at professionally typeset books, you'll see that the figure text (say the labels in a chart) is the same as the text of the article itself. Even this article suffers from the problem (but obviously, that's because the text is in a PNG so it can't scale with the article text).

The only workaround I have is to manually set the width of the figure before exporting, but this is fairly inflexible. Perhaps tikz output is another option, but my understanding (possibly incorrect) is that it isn't maintained anymore.

Can anyone recommend a good workflow for charts in R and ggplot2 to handle this situation?
