These data started life as real data derived from an affected sibling
pair study of type 1 diabetes. However, original subject and SNP
identidiers have been replaced by randomly chosen ones.
Usage
data(families)
Format
There are two objects in the loaded data file:
genotypes: An object of class
"snp.matrix" containing the SNP
genotype data for both parents and affected offspring
pedData: A data frame containing the standard six fields
for a LINKAGE pedfile. The are named familyid,
member, father, mothersex, and
affected
The two objects are linked by common row names.
Details
Coding in the pedData frame is as in the LINKAGE package,
except that missing data are coded NA rather than zero
