I'm glad you found Texample! It is an excellent site that shows many practical, and beautiful, demonstrations of the types of figures that can be constructed using LaTeX.

If a code chunk for which caching has been enabled is not changed between Sweave compilations pgfSweave and cacheSweave load stored variable values from the cache files instead of recomputing them. This hopefully saves time when all you want is to try out a different figure header or placement, not redo a whole Monte Carlo simulation. The problem is that rforge.net, which hosts the pgfSweave project, does not have these other packages. The easiest way around this is to install cacheSweave from CRAN since the dependencies are the same: install.packages('cacheSweave',dependencies=T) Then install pgfSweave: install.packages('pgfSweave',repos='http://www.rforge.net') Bugzilla from n...@jonasstein.de wrote: > > > And could someone give me an example how to write a formula in a plot? > Like plot(... title="$\sigma^2 + \int x$") > > The example you gave will work perfectly for inserting math into a plot title when using pgfSweave. The only modification is that backslashes have to be escaped so that they aren't interpreted by R as control characters. For example, you will need to use \\sigma and \\int. For direct annotation of a plot, you might consider the text() function which can be used to add labels and formulae at any arbitrary location.
