Find uninformative but available subject

Source: R/find_avail_noninform.R
find_avail_noninform.Rd

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.
