Convert a square overlap matrix to a tidy pairwise data frame

Tidies a symmetric overlap (or distance) matrix into a three-column tibble/data frame with pairs and values.

Usage

temp_overlap_df(mat)

Arguments

mat

Square numeric matrix (typically from temp_overlap_matrix()).

Value

A data frame with columns item1, item2, and distance (terminology follows stats::as.dist()).

Examples

d <- temp_overlap_matrix(ex1)
temp_overlap_df(d)
#> # A tibble: 10 × 3
#>    item1 item2 distance
