Determine the pedigree number for each ID

One of Pedigree Curation functions

Usage

findPedigreeNumber(id, sire, dam)

Arguments

id

character vector with unique identifier for an individual

sire

character vector with unique identifier for an individual's father (NA if unknown).

dam

character vector with unique identifier for an individual's mother (NA if unknown).

Value

Integer vector indicating the pedigree (family group) number for each id. Ids that are connected through parent-offspring links share the same number; numbering starts at 1.

Examples

library(nprcgenekeepr)
library(stringi)
ped <- nprcgenekeepr::lacy1989Ped
ped$gen <- NULL
ped$population <- NULL
ped2 <- ped
ped2$id <- stri_c(ped$id, "2")
ped2$sire <- stri_c(ped$sire, "2")
ped2$dam <- stri_c(ped$dam, "2")
ped3 <- ped
ped3$id <- stri_c(ped$id, "3")
ped3$sire <- stri_c(ped$sire, "3")
ped3$dam <- stri_c(ped$dam, "3")
ped <- rbind(ped, ped2)
ped <- rbind(ped, ped3)
ped$pedigree <- findPedigreeNumber(ped$id, ped$sire, ped$dam)
