Finds subjects from among available non-parents with all affection
equal to 0.
Usage
# S4 method for class 'Ped'
find_avail_noninform(obj, avail = NULL, affected = NULL)
# S4 method for class 'Pedigree'
find_avail_noninform(obj, avail = NULL, affected = NULL)
Arguments
- obj
A Ped or Pedigree object.
- avail
A logical vector with the availability status of the
individuals
(i.e. FALSE = not available,
TRUE = available,
NA = unknown).
- affected
A logical vector with the affection status of the
individuals
(i.e. FALSE = unaffected,
TRUE = affected,
NA = unknown).
Value
Vector of subject ids who can be removed by having lowest
informativeness.
Details
Identify subjects to remove from a Pedigree who are available but
non-informative (unaffected).
This is the second step to remove subjects in
shrink() if the Pedigree does not meet
the desired bit size.
If avail or affected is null, then the function will use the
corresponding Ped accessor.
Examples
data(sampleped)
ped <- Pedigree(sampleped)
