I am trying to figure out the sanctioned way for 'R CMD check pkg' to make sure that the examples in help files give the expected results.
Writing R Extensions says that check runs the help file examples (which INSTALL extracts from pkg/man/*.Rd and puts into files in pkg/R-ex). It looks like check concatenates all the example files, pkg/R-ex/*.R, into one file, pkg/pkg-Ex.R, which it runs to produce pkg/pkg-Ex.Rout. If there is an error running these files then check aborts. I don't seen anything in Writing R Extensions about checking that correct results were produced. However, in R 2.7.0, check will compare pkg/pkg-Ex.Rout to pkg/tests/Examples/pkg/pkg-Ex.Rout.save, if the latter file is in your package source, and report any differences. I don't see any mention of this and was wondering if this method should be recommended or if there was a preferred way to check help file examples for correctness. (It would be nicer if the example() function could also check for correctness, and the above method doesn't allow for that.) ---------------------------------------------------------------------------- Bill Dunlap Insightful Corporation bill at insightful dot com 360-428-8146 "All statements in this message represent the opinions of the author and do not necessarily reflect Insightful Corporation policy or position." ______________________________________________ R-devel@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/r-devel
