nonbimatch: Nonbipartite Matching
In nbpMatching: Functions for Optimal Non-Bipartite Matching

Description Usage Arguments Details Value Author(s) See Also Examples

The nonbinmatch function creates the set of pairwise matches that minimizes the sum of distances between the pairs.

1	nonbimatch(mdm, threshold = NA, precision = 6, ...)

`mdm`	A distancematrix object. See the distancematrix function.
`threshold`	An numeric value, indicating the distance needed to create chameleon matches.
`precision`	The largest value in the matrix will have at most this many digits. The default value is six.
`...`	Additional arguments, these are not used.

The nonbinmatch function calls the Fortran code (Derigs) and set of pairwise matches that minimizes the sum of distances between the pairs.

nonbimatch S4 object with several elements

`matches`	data.frame containing matches
`halves`	data.frame containing each match
`total`	sum of the distances across all pairs
`mean`	mean distance for each pair
