Adds an NA value for all animals without a relative

This allows kin to be used with setdiff when there are no relatives otherwise an error would occur because kin[['animal_with_no_relative']] would not be found. See the following: in groupAddAssign

addAnimalsWithNoRelative(kin, candidates)

Arguments

kin	dataframe with kinship values
candidates	character vector of IDs of the animals available for use in the group.

Value

A dataframe with kinships in long form after adding a row for each animal without a relative.

Details

available[[i]] <- setdiff(available[[i]], kin[[id]])

Examples

# \donttest{
examplePedigree <- nprcgenekeepr::examplePedigree
