Compute the KING-robust Matrix for a a gen_tibble object

Source: R/pairwise_king.R
pairwise_king.Rd

This function computes the KING-robust estimator of kinship.

Usage

pairwise_king(
  x,
  as_matrix = FALSE,
  block_size = bigstatsr::block_size(nrow(x))
)

Arguments

x

a gen_tibble object.

as_matrix

boolean, determining whether the results should be a square symmetrical matrix (TRUE), or a tidied tibble (FALSE, the default)

block_size

maximum number of loci read at once. More loci should improve speed, but will tax memory.

Value

a square symmetrical matrix of relationship coefficients between individuals if as_matrix is TRUE, or a tidied tibble of coefficients if as_matrix is FALSE.

Details

Note that monomorphic sites are currently considered. Remove monomorphic sites before running pairwise_king if this is a concern.
