Creates a summary count table of the number of individuals and pairs at each degree of relatedness that occurs in the UKB sample, and an optional plot.
ukb_gen_rel_count(data, plot = FALSE)A dataframe of the genetic relatedness data including KING kinship coefficient, and proportion of alleles IBS = 0. See Details.
Logical indicating whether to plot relatedness figure. Default = FALSE.
If plot = FALSE (default), a count of individuals and pairs
at each level of relatedness. If plot = TRUE, reproduces the
scatterplot of genetic relatedness against proportion of SNPs shared IBS=0
(each point representing a pair of related UKB individuals) from the
genotyping and quality control
documentation.
Use UKB supplied program `ukbgene` to retrieve genetic relatedness data file ukbA_rel_sP.txt. See UKB Resource 664. The count and plot include individuals with IBS0 >= 0.
