Assemble the composite genetic value of one phenotype from phenotype_components

Sums weight * contributor genetic value over the phenotype's component rows, one contributor lookup per row (see ?contributor_tgv). Each row reads its component_names ("total" by default) from ind_tgv, which must already hold the source traits for every contributor (.ap_materialize_tgvs()). A missing piece — a NULL dam or sire, a contributor with no ind_tgv row, a NULL group value, a NULL covariate — makes the individual's composite NA.

Usage

.assemble_composite_tgv(
  pop,
  phenotype_name,
  comp_rows,
  subset_df,
  missing_component_action
)

Arguments

comp_rows

The phenotype's phenotype_components rows.

subset_df

The planned ind_meta rows (needs id_ind, id_parent_1, id_parent_2).

missing_component_action

"skip" warns and returns NA for the excluded individuals; "error" stops. Both name the count and up to five ids.

Value

Numeric vector named by id_ind; NA marks an excluded individual.
