Description

The intersection and union slots contain the gene names as character vectors. The is.tested slot contains a Boolean label indicating whether the object has been tested or not. The cont.tbl slot contains the contingency table as a matrix. The pval and odds.ratio slots contain the p-value and odds ratio as numerics, respectively. The Jaccard slot contains the Jaccard index as a numeric.

Arguments

object

A GeneOverlap object.

Details

If the GeneOverlap object has not been tested yet, the returned Jaccard index, p-value and odds ratio will be NA, the contingency table will be an empty matrix.

Value

intersection

A character vector represents the overlapped genes.

union

A character vector represents the genes in the union of A and B.

is.tested

A Boolean represents whether the overlapping test has been performed or not.

cont.tbl

A matrix represents the contingency table.

pval

A numeric represents the significance of overlap.

odds.ratio

A numeric represents the odds ratio in comparison to the genomic background.

Jaccard

A numeric represents the Jaccard index between two sets.
