Sample datasets to illustrate data input
The first five files concern data on 20 diallelic loci on 120 subjects. These data are distributed with the Haploview package (Barrett et al., 2003). The sixth files contains a additional dataset of 18 SNPs in 100 subjects, coded in "long" format, and the seventh file duplicates this dataset in an alternative long format. These seven files are used in the data input vignette. The final file is a sample imputed genotype dataset distributed with the MACH imputation package, and used in the imputation vignette.
These files are stored in the
extdata relative to the
package base. Full file names can be obtained using the
The following files are described here:
sample.ped.gz: A gzipped pedfile
sample.info: An accompanying locus information file
sample.bed: The corresponding PLINK
sample.bim: The PLINK
sample.fam: The PLINK
sample-long.gz: A sample of long-formatted data
sample-long-alleles.gz: The same as above, but allele-coded
mlproboutput file from the MACH genotype imputation program. This file contains, for each imputed genotype call, posterior probabilities for the three possible genotypes
