Creating good examples is hard, but so is creating a research compendium following the ideas of Reproducible Research of Donoho and others at Stanford, called Literate Statistical Practice in the statistical community. The tools are there in R for this purpose (vignettes, etc.) but they seem to be rarely used for this purpose.

One reason examples are hard is that they are often isolated from the research itself, and hard to understand out of context. The notion of a Research Compendium that includes this context might help.

But this requires a fair amount of work, and I don't think it is currently rewarded in the publication process (Journals do not require it).

The creation of a research compendium can be viewed as a form of unit testing, and the fact that R has powerful tools that support this process (Sweave) could be viewed as one of its outstanding features (relating these comments back to the topic of this thread).

A list of references on Reproducible Research and LSP can be found in the package cxxPack. A template for creating a compendium can also be found there.
