(One question from the thread Handling Not-Always-Needed Dependencies?) I hope not to start another long tangled thread, but I have a basic confusion which I think has a yes/no answer and I would like to know if there is agreement on this point (or is it only me that is confused as usual). If my package has a test that needs another package, but that package is not needed in the /R code of my package, then I indicate it as "Suggests", not as "Depends" nor as "Imports". If that package is not available when I run R CMD check, should the test pass? Yes or no: ?
Yes, as the package should pass the checks if suggested packages are unavailable. BUT if these are available and the code is wrong, then it should generate an error.

(I realize my own answer might be different if the package was used in an example or demo in place of a test, but that is just the confusion caused by too many uses for Suggests. In the case of a test, my own thought is that the test must fail, so my own answer is no. If the test does not fail then there is no real testing being done, thus missing code coverage in the testing. If the answer is no, then the tests do not need to be run if the package is not available, because it is known that they must fail. I think that not bothering to run the tests because the result is known is even more efficient than other suggestions. I also think it is the status quo.) Hoping my confusion is cleared up, and this does not become another long tangled thread, Paul ______________________________________________ R-package-devel@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/r-package-devel
