Arguments

M

an ancestry-match matrix

amm2tibble() returns a tibble with three columns:

  • x: the 1-based index of the row of input matrix,

  • y: the 1-based index of the column of the input matrix,

  • amm: the logical value (TRUE/FALSE) of the (x,y)-th cell of the input matrix.

Examples

# convert one of the simple example AMMs to a tibble
amm2tibble(example_amms$Father_Offspring_2gen)
#> # A tibble: 49 × 3
#>        x     y amm  
#>    <int> <int> <lgl>
#>  1     1     1 FALSE
#>  2     2     1 TRUE 
#>  3     3     1 FALSE
