| check_sim {iGraphMatch} | R Documentation |
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
