read_quadtree: Read/write a 'Quadtree'

In quadtree: Region Quadtrees for Spatial Data

Read/write a Quadtree

Description

Reads and writes a Quadtree.

Usage

## S4 method for signature 'character'
read_quadtree(x)

## S4 method for signature 'character,Quadtree'
write_quadtree(x, y)

Arguments

x	character; the filepath to read from or write to
y	a Quadtree

Details

To read/write a quadtree object, the C++ library cereal is used to serialize the quadtree and save it to a file. The file extension is unimportant - it can be anything (I've been using the extension '.qtree').

Value

read_quadtree() - returns a Quadtree

write_quadtree() - no return value

Examples

library(quadtree)
habitat <- terra::rast(system.file("extdata", "habitat.tif", package="quadtree"))

qt <- quadtree(habitat, .1)

path <- tempfile(fileext = "qtree")
write_quadtree(path, qt)
qt2 <- read_quadtree(path)
