make_family_id: Construct family id vector from pedigree trio information

In ekstroem/networkR: Network Analysis and Visualization

Description

Create a vector of length n, giving the family id of each subject. If the pedigree is totally connected, then everyone will end up in tree 1, otherwise the tree numbers represent the disconnected subfamilies. Singleton subjects each have unique family numbers.

No check is done to ensure that the id, fid, and mid actually refer to proper family structure. References to ids in the fid and mid arguments that are not part of the id vector are considered founders and are thus replaced by NA or 0s after being used to group full and half-sibs.

Usage

make_family_id(id, fid, mid)

Arguments

id	Numeric vector of ids
fid	Numeric vector of ids of the father. This should be NA or 0 for a founder.
mid	Numeric vector of ids of the mother. This should be NA or 0 for a founder.

Value

Returns an integer vector giving the family index of each individual
