SNPlocations {repfdr}

Three GWAS studies SNPs locations and data

Description

SNPlocations includes the locations of SNPs in chromosomes 1 to 4. Data was simulated to the SNPs with HAPGEN2 for three studies and a sample of it was taken (Chromosomes 1 to 4) for the examples. The data is summarized as z-scores(transformed p-values, with inverse standard normal cumulative distribution). The z-scores matrix can be download from the web (see example).

Usage

data(SNPlocations)

Format

SNPlocations data.frame of 249024 SNPs' names, chromosome number and location on the chromosomes. zmat Matrix of 249024 SNPs' z-scores (in rows) in each of the 3 studies (columns).
