Description Usage Arguments Value
Extract genes from a limma-fit object (resulting from an eBayes call) that
are differentially expressed. Two different methods are used for calling
differential expression:
any_probe
- at least one probe for that gene must be differentially
expressed.
all_probes
- every probe for that gene must be differentially
expressed (and must be differentially expressed in the same direction).
This doesn't return information about the direction of change, and only
returns a vector of gene symbols or ids, as extracted from the genes
dataframe in the limma-fit object fit
.
