kindepth: Compute the depth of each subject in a pedigree
Description
Mark each person as to their depth in a pedigree;
0 for a founder, otherwise depth = 1 + max(father's depth, mother's
depth)
Usage
kindepth(id, dad.id, mom.id, align = FALSE)
Arguments
id
Identification code for each individual
dad.id
Id code for the father
mom.id
Id code for the mother
align
If align=T, go one step further and try to make both
parents of each child have the same depth.
(This is not always possible). It helps
the drawing program by lining up pedigrees that "join in the middle"
via a marriage.
Value
an integer vector containing the depth for each subject
Details
In the case of an inbred pedigree a perfect alignment obeying
extra=TRUE may not exist.
