computeMsigOverlap {vissE} | R Documentation |
Compute overlap between gene sets from a GeneSetCollection using the Jaccard index or the overlap coefficient. These values can then be used to compute a network of gene set overlaps.
computeMsigOverlap( msigGsc1, msigGsc2 = NULL, thresh = 0.25, measure = c("jaccard", "ovlapcoef") )
msigGsc1 |
a GeneSetCollection object. |
msigGsc2 |
a GeneSetCollection object or NULL if pairwise overlaps are to be computed. |
thresh |
a numeric, specifying the threshold to discard pairs of gene sets. |
measure |
a character, specifying the similarity measure to use:
|
a data.frame, containing the overlap structure of gene sets represented as a network in the simple interaction format (SIF).
