TTN data set
Description
These data have been extracted from the 1000 Genomes data.
The data set contains the genotype matrix TTN.gen
, the pedigree matrix TTN.fam
and a matrix TTN.bim
,
corresponding to 503 individuals of European populations and 733 SNPs on chromosome 2, on a ~600kb segment
containing the Titin gene. There is also a factor TTN.pop
, which gives the population from which each
individual is drawn (CEU = Utah residents of Northern Western European ancestry, FIN = Finnish, GBR = England and Scottland,
IBS = Iberian, TSI = Toscani).
Usage
data(TTN)
Format
There are three data objects in the dataset:
TTN.gen
Genotype matrix
TTN.fam
Data frame containing all variables corresponding to a
.fam
fileTTN.bim
Data frame containing all variables corresponding to a
.bim
fileTTN.pop
Factor giving the population from which each individual is drawn
Source
The data were obtained from the 1000 Genomes project (see https://www.internationalgenome.org/).
