In LTFGRS: Implementation of Several Phenotype-Based Family Genetic Risk Scores

Attach attributes to a family graphs

Description

This function attaches attributes to family graphs, such as lower and upper thresholds, for each family member. This allows for a user-friendly way to attach personalised thresholds and other per-family specific attributes to the family graphs.

Usage

attach_attributes(
  cur_fam_graph,
  cur_proband,
  fid,
  attr_tbl,
  attr_names,
  censor_proband_thrs = TRUE
)

Arguments

cur_fam_graph	An igraph object (neighbourhood graph around a proband) with family members up to degree n.
cur_proband	Current proband id (center of the neighbourhood graph).
fid	Column name of family id.
attr_tbl	Tibble with family id and attributes for each family member.
attr_names	Names of attributes to be assigned to each node (family member) in the graph.
censor_proband_thrs	Should proband's upper and lower thresholds be made uninformative? Defaults to TRUE. Used to exclude proband's information for prediction.

Value

igraph object (neighbourhood graph around a proband) with updated attributes for each node in the graph.
