ped: Genotypic dataset in PED format
Description
This dataset contains the genotypes of 2000 SNPs to be used with the tutorial for
assessing the statistical power of GWAs with waffect (see the vignette). It has 100 rows (one
for each individual) and 2007 columns:
- fam_id: family ID, here an integer from 1 to 100
- ind_id: individual ID, an integer from 1 to 100
- pat_id: paternal ID, here a dummy variable set to 0 for all individuals
- mat_id: maternal ID, dummy variable
- sex: all females (coded by 2)
- pheno: observed phenotypes; codes: case = 2, control = 1.
Genotypes (column 7 onwards) are biallelic, one allele for each column. For instance,
columns 7 and 8 contain the two alleles for SNP1 and columns 9 and 10 contain the alleles
for SNP2. Before using this dataset with PLINK it is necessary to save it into a file with
extension .ped (see the vignette). The genotypes were obtained from public data released by
the 1000 Genomes Projects.
