computeHpIC: Compute Information Content (IC) for each HP based on genes by HP

Description

Compute Information Content (IC) for each HP based on genes by HP

Usage

computeHpIC(content, hp.descendants)

Arguments

content

a list providing the content associated to each HP

hp.descendants

a list providing for each HP all its descendant HP terms

Value

a vector of IC named with HP terms

Details

This function assumes that all the HP terms taken into account belong to the same family of terms(i.e they are all descendants of the same term).

Examples
