Internal function that checks that a similarity matrix satisfies necessary conditions and modifies it for use in graph matching.
check_sim(sim, seeds, nonseeds, totv1, totv2, for_nonseeds = TRUE)Standardized similarity matrix for similarities only between nonseeds across the two graphs, if for_nonseeds = TRUE, or between all nodes, if for_nonseeds = FALSE
Similarity matrix
dataframe of seed matches from running check_seeds
dataframe of nonseed nodes from running check_seeds
total number of vertices in the first graph
total number of vertices in the second graph
Whether the similarities are between non-seed nodes only (default = TRUE), or if similarities among seed nodes are included (FALSE)
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.
