Determines the incidence of a gene set in a list of genes.

Description

Calculates the incidence of a gene set in an experiment

Usage

1
  getIncidence(universeIDs, set)

Arguments

universeIDs

A vector containing the list of possible gene ids in the universe (or experiment).

set

A GeneSet object containing a set of genes of interest

Details

getIncidence returns an incidence vector of the location of the genes within a gene set in a list of genes in an experiment and vise-versa.

Value

A list of inSet and inExp. inSet is a vector with the same length as universeIDs. Each value of inSet is 1 if the gene is in the set and 0 otherwise. inExp is a vector with the same length as geneIds(set), the number of genes in the set. Each value of inExp is 1 if the gene is in universeIDs and 0 otherwise.
