Render Boolean Distance

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

if(run_documentation()){
#Measure distance to
plot_image(render_boolean_distance(t(volcano) > 150))
plot_image(render_boolean_distance(t(volcano) < 150))
}
if(run_documentation()){
#If we want to rescale this to zero to one (to visualize like an image), set rescale=TRUE
plot_image(render_boolean_distance(t(volcano) > 150,rescale=TRUE))
}
