There is a mechanism for testing code in R packages (R CMD check), see
the Writing R extensions manual. If you need more flexibility for your
tests, you could look at RUnit on CRAN, or svUnit on R-Forge
(http://r-forge.r-project.org, on CRAN soon). For the later one, you
install it by:
install.packages("svUnit",
repos="http://R-Forge.R-project.org")
These is a vignette associated with svUnit:
vignette("svUnit")
Note that RUnit and svUnit are "test suite code" compatible, but they
use very different mechanisms internally.
Best,
Philippe Grosjean

Hi Nathan, in addition to what others have already mentioned there is some documentation in the Writing R Extensions Manual: - on the supported structure of packages, indicating where test code might be added http://stat.ethz.ch/R-manual/R-patched/doc/manual/R-exts.html#Package-subdirectories - and the recommended standard approach to check a package http://stat.ethz.ch/R-manual/R-patched/doc/manual/R-exts.html#Checking-and-building-packages and a wiki article on how to combine the standard check (viz R CMD check) with any of the unit testing approaches http://wiki.r-project.org/rwiki/doku.php?id=developers:runit&s=unit%20test Examples for the standard approach employed by R can be found in the R source repository https://svn.r-project.org/R/trunk/src/library/stats/tests/ and for unit test based checking e.g. Rmetrics http://r-forge.r-project.org/plugins/scmsvn/viewcvs.php/pkg/?root=rmetrics or BioConductor examples https://hedgehog.fhcrc.org/bioconductor/trunk/madman/Rpacks/Biobase/inst/UnitTests/ where you need the access info provided here http://wiki.fhcrc.org/bioc/DeveloperPage Regards, Matthias Nathan S.
