Count first-order relatives.

Part of Relations

Usage

countFirstOrder(ped, ids = NULL)

Arguments

ped

: Pedigree Standardized pedigree information in a table.

ids

character vector of IDs or NULL These are the IDs to which the analysis should be restricted. First-order relationships will only be tallied for the listed IDs and will only consider relationships within the subset. If NULL, the analysis will include all IDs in the pedigree.

Value

A dataframe with column id, parents, offspring, siblings, and total. A table of first-order relationship counts, broken down to indicate the number of parents, offspring, and siblings that are part of the subset under consideration.

Details

Tallies the number of first-order relatives for each member of the provided pedigree. If 'ids' is provided, the analysis is restricted to only the specified subset.
