Are you able to reproduce the problem if you run R CMD check (for example) in a virtual machine without a working Python installation? It would explain the situation if the process was stuck asking the user for (e.g.) permission to install miniconda, but these prompts are all guarded by tests for interactive() and therefore shouldn't be happening. -- Best regards, Ivan __ R-package-devel@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/r-package-devel
Re: [R-pkg-devel] A simple question regarding examples
Hello Duncan and Ivan, Thank you for your prompt response! Perhaps I should add that: I don't think the Python module "ctef" exists on CRAN. Therefore, I am very surprised that the example below runs overtime, since all it has to do is to run reticulate::py_module_available('ctef'). If even this part is running overtime, I am not quite sure how to deal with it. #' if (reticulate::py_module_available('ctef')) { #' res <- my_func(input1, input2) #' } Looking forward to your reply.

R will run tests based on what is in the my_func.Rd examples section. I'd guess that's pretty similar to your second version (except for the \dontrun part, which you shouldn't use, as Ivan said).

The \examples section should include running code, which example(your_func) should run. If there's only the \dontrun{} section, it won't pass the review. For things that ought to work, it's best to reduce inputs further until the example runs within the time limit. One remaining escape hatch is \donttest{}, but R CMD check --as-cran still involves running \donttest{} examples. Putting the whole example in a \donttest{} section doesn't sound like a good idea either. -- Best regards, Ivan __ R-package-devel@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/r-package-devel
