listbdsmatrix {bdsmatrix} | R Documentation |
This routine is the inverse of the bdsmatrix.ibd function found in the kinship library.
listbdsmatrix(x, id = TRUE, diag = FALSE)
x |
a |
id |
if true, the dimnames of the object are used as the row and column identifiers in the output, if false integer row and column numbers are used |
diag |
include the diagonal elements in the output |
The non-zero elements of the matrix are listed out as row-col-value triplets, one per line, in a data frame. Since the matrix is known to be symmetric, only elements with row >= col are listed. When familial correlation data is represented in a bdsmatrix, e.g. kinship or identity-by-descent information, the diagonal is a known value and can be omitted from the listing. Genetic software often produces matrices in the list form; this routine is the inverse of the bdsmatrix.ibd routine, found in the kinship library, which converts list form to bdsmatrix form.
