[R-pkg-devel] Problem passing noSuggests test

[Jon Olav Skoien]

One of my packages failed the noSuggests test, and needs to be
updated. Fair enough, a suggested package was used unconditionally
both in an example and in a test. From what I understood, a solution
is to wrap this part of the code inside
if (require("suggestedPackage")) {useSuggestedPackage}
However, it still fails the noSuggests test, this time because the
output does not match the test.Rout.save-file. This is also clear, as
some of the code is not executed, and some output is missing.

How do I get around this?
I could use ## IGNORE_RDIFF_BEGIN and ## IGNORE_RDIFF_END before and
after the if (require())  clause, but then this part would not be
tested when the suggested package is available either. I don't like
this solution, as it means the interaction between the two packages
will not be checked.

Am I missing something? Is there a different way of conditionally
using the suggested package? Or do I have to use the IGNORE_RDIFF
method?

Thanks,
Jon
