What are good example R packages written using RUnit or roxygen?

Question

I'm writing an R package that's going to be used by others, so I'm trying to get this one right! I want to use roxygen for documentation and RUnit for unit testing, but I haven't used them before.

What packages exist (either on CRAN or elsewhere) that use either of these tools well?

Answer 1

Roxygen is used in Hadley's stringr (see also this previous SO question: R documentation with Roxygen), mutatr and testthat packages.

But testthat is used for testing in the mentioned packages instead of RUnit.

Answer 2

If you look at the RUnit page at CRAN you see the list of of packages that have a Depends:, Imports: or Suggests: on it. Maybe try one of those? The list includes plyr and a bunch of Rmetrics packages.

Likewise, the roxygen page at CRAN can be looked at but it only lists a single package.
