Description

Takes an matrix (or and returns the nearest distance to each TRUE.

Usage

render_boolean_distance(boolean, rescale = FALSE)

Arguments

`boolean`	Logical matrix (or matrix of 1s and 0s), where distance will be measured to the `TRUE` values.
`rescale`	Default `FALSE`. Rescales the calculated distance to a range of 0-1. Useful for visualizing the distance matrix.

Value

Matrix of distance values.

Examples

#Measure distance to
image(render_boolean_distance(volcano > 150))
image(render_boolean_distance(volcano < 150))

#If we want to rescale this to zero to one (to visualize like an image), set rescale=TRUE
plot_image(render_boolean_distance(volcano > 150,rescale=TRUE))
