check_sim: Check the similarity matrix passed to a matching function

In dpmcsuss/iGraphMatch: Tools for Graph Matching

Check the similarity matrix passed to a matching function

Description

Internal function that checks that a similarity matrix satisfies necessary conditions and modifies it for use in graph matching.

Usage

check_sim(sim, seeds, nonseeds, totv1, totv2, for_nonseeds = TRUE)

Arguments

sim	Similarity matrix
seeds	dataframe of seed matches from running check_seeds
nonseeds	dataframe of nonseed nodes from running check_seeds
totv1	total number of vertices in the first graph
totv2	total number of vertices in the second graph
for_nonseeds	Whether the similarities are between non-seed nodes only (default = TRUE), or if similarities among seed nodes are included (FALSE)

Details

The goal here is to be flexible in terms of the dimensions of the similarity matrix passed to gm. This is useful when the graphs have different orders in which case the function accepts matrices with dimensions equal to that of orders of the original graphs or the number of nonseeds.

Value

Standardized similarity matrix for similarities only between nonseeds across the two graphs, if for_nonseeds = TRUE, or between all nodes, if for_nonseeds = FALSE
