Why is nproc=0 for fgsea in GSEA function?

[robertwinkler-research]

Dear YuLab,

first thanks for your contributions.
I was wondering why is nproc specified nproc = 0 when clusterProfiler::GSEA calls fgsea? Could it be passed on instead? Not having the option makes GSEA very slow, even though I prefer GSEA to using fgsea directly due to convenience.

tmp_res <- fgsea(pathways=geneSets,
stats=geneList,
minSize=minGSSize,
maxSize=maxGSSize,
eps=eps,
gseaParam=exponent,
nproc = 0,
...)

Thank you!

Edit: I noticed this pertains more to DOSE...
