## Prerequisite
data(geneByHp, hp_descendants, package="PCAN")
geneByHp <- unstack(geneByHp, entrez~hp)
ic <- computeHpIC(geneByHp, hp_descendants)

## Compute similarity between different couples of HP terms
data(hp_ancestors, hpDef, package="PCAN")
hp1 <- "HP:0000518"
hp2 <- "HP:0030084"
hp3 <- "HP:0002119"
hp4 <- "HP:0001305"
hpDef[which(hpDef$id %in% c(hp1, hp2)), 1:2]
calcHpSim(hp1, hp2, IC=ic, ancestors=hp_ancestors)
hpDef[which(hpDef$id %in% c(hp2, hp3)), 1:2]
calcHpSim(hp2, hp3, IC=ic, ancestors=hp_ancestors)
hpDef[which(hpDef$id %in% c(hp2, hp4)), 1:2]
calcHpSim(hp2, hp4, IC=ic, ancestors=hp_ancestors)
hpDef[which(hpDef$id %in% c(hp3, hp4)), 1:2]
calcHpSim(hp3, hp4, IC=ic, ancestors=hp_ancestors)
