Hi Kevin,

I have not looked at BioC's licensing requirements, but presumably, they are ok with the non-commercial use restrictions placed on users of cytolib, thus also on flowCore.

If you want your package to be on CRAN, those restrictions on users are not allowed by CRAN's policy:

https://cran.r-project.org/web/packages/policies.html

"Such packages are not permitted to require (e.g., by specifying in ‘Depends’, ‘Imports’ or ‘LinkingTo’ fields) directly or indirectly a package or external software which restricts users or usage."


Thus, you would seem to need to make a decision on hosting your package on CRAN, but without the need to import from flowCore/cytolib, or consider hosting your package on BioC, with the attendant restrictions on commercial use.
