as.list: Coerce a Spat* object to a list

In terra: Spatial Data Analysis

Coerce a Spat* object to a list

Description

Coerce a SpatRaster, SpatRasterCollection, SpatRasterDataset, SpatVector or SpatVectorCollection to a list. With a SpatRaster, each layer becomes a list element. With a SpatRasterCollection or SpatRasterDataset, each SpatRaster becomes a list element. With a SpatVector, each variable (attribute) becomes a list element. With a SpatVectorCollection, each SpatVector becomes a list element.

Usage

## S4 method for signature 'SpatRaster'
as.list(x, geom=NULL, ...)

## S4 method for signature 'SpatRasterCollection'
as.list(x, ...)

## S4 method for signature 'SpatVector'
as.list(x, geom=NULL, ...)

## S4 method for signature 'SpatVectorCollection'
as.list(x, ...)

Arguments

x	SpatRaster, SpatRasterDataset, SpatRasterCollection, or SpatVector
geom	character or NULL. If not NULL, and x is a SpatVector, it should be either "WKT" or "HEX", to get the geometry included in Well-Known-Text or hexadecimal notation. If x has point geometry, it can also bey "XY" to add the coordinates of each point. If x is a SpatRaster, any value that is not NULL will return a list with the the parameters describing the geometry of the SpatRaster are returned
...	additional arguments. These are ignored

Value

list

Examples

f <- system.file("ex/lux.shp", package="terra")
v <- vect(f)
as.list(v)


s <- rast(system.file("ex/logo.tif", package="terra")) + 1  
as.list(s)
