Individual inbreeding coefficient

indiv_inbreeding.Rd

This function calculates the inbreeding coefficient for each individual based on the beta estimate from Weir and Goudet (2017).

Usage

indiv_inbreeding(.x, method = c("WG17"), allele_sharing_mat = NULL, ...)

# S3 method for class 'tbl_df'
indiv_inbreeding(.x, method = c("WG17"), allele_sharing_mat = NULL, ...)

# S3 method for class 'vctrs_bigSNP'
indiv_inbreeding(.x, method = c("WG17"), allele_sharing_mat = NULL, ...)

# S3 method for class 'grouped_df'
indiv_inbreeding(.x, method = c("WG17"), allele_sharing_mat = NULL, ...)

Arguments

.x

a vector of class vctrs_bigSNP (usually the genotype column of a gen_tibble object), or a gen_tibble.

method

currently only "WG17" (for Weir and Goudet 2017).

allele_sharing_mat

optional and only relevant for "WG17", the matrix of Allele Sharing returned by pairwise_allele_sharing() with as_matrix=TRUE. As a number of statistics can be derived from the Allele Sharing matrix, it it sometimes more efficient to pre-compute this matrix. It is not possible to use this with grouped tibbles.

...

currently unused.

Value

a numeric vector of inbreeding coefficients.
