This is a convenience wrapper around [addParentalChain()] with `component = "dadID"`.

Usage

addPaternalChain(
  ped,
  personID = "personID",
  dadID = "dadID",
  momID = "momID",
  chain_col = "dadID_chain",
  chain_string_col = "dadID_chain_string",
  collapse = "|",
  traversal_direction = "in"
)

Arguments

ped: A pedigree data frame.
personID: Character string giving the name of the column containing individual IDs.
dadID: Character string giving the name of the column containing paternal IDs.
momID: Character string giving the name of the column containing maternal IDs.
chain_col: Character string giving the name of the output list-column that will contain the ordered parental ancestor chain for each individual.
chain_string_col: Character string giving the name of the output character column that will contain the collapsed parental ancestor chain.
collapse: Character string used to collapse ancestor IDs into `chain_string_col`.
traversal_direction: Character giving the mode of transversion: defaults to "in". If set to out, will procedure a list of descendants.

Value

A data frame with two added columns:

`chain_col`: A list-column containing the ordered paternal ancestor chain for each individual.
`chain_string_col`: A character column containing the collapsed paternal ancestor chain, or `NA_character_` when no paternal ancestors are found.
