SNPlocations: Three GWAS studies SNPs locations and data

Description Usage Format Source Examples

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

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).
