R: Finds the minimum distances between pairs of individuals...

gen.find.Min.Distance.MRCA {GENLIB} | R Documentation

## Finds the minimum distances between pairs of individuals given a set of ancestors.

### Description

Returns the shortest distances (number of meioses) between pairs of probands given the matrix of MRCAs output by the gen.findMRCA function.

### Usage

    gen.find.Min.Distance.MRCA(genMatrix, individuals="ALL", ancestors="ALL")

### Arguments

`genMatrix` | Matrix of most recent common ancestors, MRCAs, obtained with gen.findMRCA. Required.
`individuals` | Vector of proband id numbers to include. All are included by default.
`ancestors` | Vector of MRCA id numbers to include. All are included by default.

### Value

returns a matrix

### Examples

    data(geneaJi)
    genJi<-gen.genealogy(geneaJi)
    matMRCA<-gen.findMRCA(genJi, individuals=c(1,29), NbProcess = 1)
    gen.find.Min.Distance.MRCA(matMRCA)

    # Increasing NbProcess will decrease execution time
    data(genea140)
    gen140<-gen.genealogy(genea140)
    matMRCA<-gen.findMRCA(gen140, individuals=c(409033,408728,408828), NbProcess = 1)
    gen.find.Min.Distance.MRCA(matMRCA, individuals=c(409033,408728))
