I am facing a problem when I try to run the function gseDO() from the library DOSE. However, the author of DOSE, Guangchuang Yu, could NOT reproduce it, but it rather seems to be a windows-specific issue related to an export/ import issue from BiocParallel. Hence I decided to post here on the BioC forum.

Please also see this thread on GitHub site of DOSE here.

Error: 'mcparallel' is not an exported object from 'namespace:parallel'
In addition: Warning message:
