testdata {snpMatrix} | R Documentation |
This dataset comprises several data frames from a fictional (and unrealistically small) study. The dataset started off as real data from a screen of non-synonymous SNPs for association with type 1 diabetes, but the original identifiers have been removed and a random case/control status has been generated.

There are five data objects in the dataset:
Autosomes

genotype calls for 400 subjects at 9445 autosomal SNPsXchromosome
"X.snp.matrix"
containing
genotype calls for 400 subjects at 155 SNPs on the X chromosomeAsnps

The data were obtained from the diabetes and inflammation laboratory (see http://www-gene.cimr.cam.ac.uk/todd)
