[R-pkg-devel] package dependencies are not available on some check severs

[Miao YU]

Thanks! I checked the error and found the original error came from another package(mzR) which are imported by xcms and MSnbase. Unfortunately, the functions I needed are not so self-contained and also rely on mzR in some certain cases.

Good news is that someone has recently raised same check error issue on Github(https://github.com/sneumann/mzR/issues/143) and the author has shown a solution for this issue. Maybe a few days later mzR could be updated on Bioc without error and then I will try to submit my package again.
