Test data for the snpMatrix package

Description

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.

Usage

data(testdata)

Format

There are five data objects in the dataset:

Autosomes
An object of class "snp.matrix" containing genotype calls for 400 subjects at 9445 autosomal SNPs
Xchromosome
An object of class "X.snp.matrix" containing genotype calls for 400 subjects at 155 SNPs on the X chromosome
Asnps
A dataframe containing information about the autosomal SNPs. Here it contains only one variable, chromosome, indicating the chromosomes on which the SNPs are located
Xsnps
A dataframe containing information about the X chromosome SNPs. Here it is empty and is only included for completeness
subject.data
A dataframe containing information about the subjects from whom each row of SNP data was obtained. Here it contains:
