subset_kinship {qtl2pleio}

Subset a kinship matrix to include only those subjects present in all inputs

Description

Since a kinship matrix has subject ids in both rownames and colnames, so we need to remove rows and columns according to names in 'id2keep'. We first remove rows and columns of subjects that are not in 'id2keep'. We then order rows and columns of the resulting matrix by the ordering in 'id2keep'.

Usage

subset_kinship(kinship, id2keep)

Arguments

kinship

a kinship matrix

id2keep

a character vector of subject ids to identify those subjects that are shared by all inputs
