kinMatrix2LongForm: Reformats a kinship matrix into a long-format table.

In rmsharp/nprcmanager: Genetic Tools for Colony Management

Description

Part of Group Formation

Usage

kinMatrix2LongForm(kinMatrix, rm.dups = FALSE)

Arguments

kinMatrix	numerical matrix of pairwise kinship values. The row and column names correspond to animal IDs.
rm.dups	logical value indication whether or not reverse-order ID pairs be filtered out? (i.e., "ID1 ID2 kin_val" and "ID2 ID1 kin_val" will be collapsed into a single entry if rm.dups = TRUE)

Value

A dataframe with columns id1, id2, and kinship. This is the kinship data reformatted from a matrix, to a long-format table.

Examples

library(nprcgenekeepr)
ped <- nprcgenekeepr::lacy1989Ped
ped$gen <- findGeneration(ped$id, ped$sire, ped$dam)
kmat <- kinship(ped$id, ped$sire, ped$dam, ped$gen)
reformattedKmat <- kinMatrix2LongForm(kmat, rm.dups = FALSE)
nrow(reformattedKmat)
reformattedNoDupsKmat <- kinMatrix2LongForm(kmat, rm.dups = TRUE)
nrow(reformattedNoDupsKmat)
