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.
