[R-pkg-devel] Strange error from CRAN on package submission

[Kevin R. Coombes]

Hi Uwe,

Thanks for the suggestion. I thought of that idea last night, and tried 
it with the latest submission of version 0.11.4 of Mercator. That 
version is still in the submission queue waiting for manual inspection, 
but it gave the same error message. (See 
https://win-builder.r-project.org/incoming_pretest/Mercator_0.11.4_20201111_014655/Debian/00check.log)

I think I may try to "Import" or "Depend" on flexmix to force it to be 
available.

Is there some reason why my program should even need to know that 
flexmix is suggested several layers down the dependency hierarchy? For 
building and installing the package (or running R CMD check ---as-cran), 
I tried on my machine when flexmix is not even installed, and got no 
errors or warnings.

There is clearly something I don't understand about namespaces, and I'd 
like to learn it to avoid this kind of situation in the future.

Best,
   Kevin
