                    Hi,
The checks of compartmap fail on Linux due to missing Suggest declarations for csaw, BiocStyle and SingleCellExperiment:

Thank you for your response, James!
BiocStyle is installed:
It is part of the builder setup steps.
But if a dependency does not declare explicitly that it needs it then it is not visible/usable to the package.
See _R_CHECK_SUGGESTS_ONLY_=true for more details.
