Identifies identical samples within SNP blocks.
check.identical.samples.by.block(genotypes, blcsize, threshold = 0)
Arguments
- genotypes
Genotype matrix.
- blcsize
Block size (number of SNPs).
- threshold
Distance threshold. Default 0.
Value
List of identical sample pairs.
Examples
set.seed(1)
mat <- matrix(sample(1:3, 40, TRUE), nrow = 4)
rownames(mat) <- paste0("S", 1:4)
check.identical.samples.by.block(mat, blcsize = 5, threshold = 0)
