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.
