Takes an matrix (or and returns the nearest distance to each TRUE.
render_boolean_distance(boolean, rescale = FALSE)
Logical matrix (or matrix of 1s and 0s), where distance will be measured to the TRUE
values.
Default FALSE
. Rescales the calculated distance to a range of 0-1.
Useful for visualizing the distance matrix.
Matrix of distance values.
