Part of Relations
countFirstOrder(ped, ids = NULL)
| 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. |
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.
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.
