Description Usage Arguments Details Value Author(s) Examples

jaccard_dist calculates the pairwise distance of genes in an interaction network.

1	jaccard_dist(gene1, gene2, graph)

`gene1`	Character, HGNC symbol of the first gene.
`gene2`	Character, HGNC sysmbol of the second gene
`graph`	igraph object representing the network

Jaccard similarity of 2 nodes in the gene network is calculated. Jaccard similarity is the number of common neighbors divided by the number of vertices that are neighbors of at least one of the 2 nodes. Distance is then obtained by taking 1 - similarity.

Numeric, distance score
