makePedigreeNumeric {pedantics} | R Documentation |
Some internal pedantics
modules require that pedigrees be
specified only by numerical values, including numerical values
for missing data, this provides that conversion
makePedigreeNumeric(id, sire, dam, missingVal = NULL)
id |
Individual identifiers - pass using as.character() |
sire |
Sire codes - pass using as.character() |
dam |
Dam codes - pass using as.character() |
missingVal |
the indicator that should be substituted for missing values |
numericPedigree |
The factor pedigree in numeric form |
idKey |
A key to facilitate conversion back to the original identifiers |
