Hi, Hervé.

Thank you for making this clear to me. I will try to think of an optimal solution for this. The issue here is that my package works as the pipeline itself, similarly to how ORFik works.

Out of curiosity, I just checked how ORFik and KnowSeq handle this situation:

  *   for STAR, for instance, ORFik simply comments the function that runs STAR in @examples (https://github.com/Roleren/ORFik/blob/master/R/STAR.R). Quite a hacky solution to avoid the overuse of \donttest{}.
  *   KnowSeq includes a function to download all external software (https://github.com/CasedUgr/KnowSeq/blob/75d5d9f526f5b4ac561455a46884fe0a1860ffa0/R/sraToFastq.R), and it includes \donttest{} in some functions.

I will see if I can include \donttest{} in as many functions with external dependencies as I can and add some other dependencies in SystemRequirements to satisfy the 80% testable code in @examples.

Hi Fabricio,

If your package requires external software/libraries/tools in order to
pass 'R CMD build' and 'R CMD check', then please list them in the
SystemRequirements field of your DESCRIPTION file. In addition, we
kindly ask you to provide an INSTALL file in the top-level folder of
your package source tree that documents how to install these external
deps on all the supported platforms.

BTW I'm not sure that KnowSeq or ORFik have external system
requirements. I don't see that they have a SystemRequirements field.
Only openPrimeR has one but it's not clear to me that the package
actually needs all the things listed there e.g. for example MAFFT is
listed but we don't have it on the build machines.

FWIW most packages avoid having to depend on external tools like
SRAtoolkit, STAR or salmon by assuming that this step of the analysis
was already taken care of, and by focusing on the downstream analysis.
These packages often include the output of the upstream analysis as a
small dataset and start from there.

Hope this helps,

I have seen other Bioc packages with external dependencies, such as KnowSeq (https://bioconductor.org/packages/release/bioc/html/KnowSeq.html), ORFik (https://www.bioconductor.org/packages/release/bioc/html/ORFik.html), and openPrimeR (https://bioconductor.org/packages/release/bioc/html/openPrimeR.html), but it is not clear how they handle the dependencies in the Bioconductor build system.
