coerce: Coercion to vector, matrix or array

In terra: Spatial Data Analysis

Coercion to vector, matrix or array

Description

Coercion of a SpatRaster to a vector, matrix or array. Or coerce a SpatExtent to a vector or matrix

Usage

## S4 method for signature 'SpatRaster'
as.vector(x, mode='any')

## S4 method for signature 'SpatRaster'
as.matrix(x, wide=FALSE, ...)

## S4 method for signature 'SpatRaster'
as.array(x)

## S4 method for signature 'SpatExtent'
as.vector(x, mode='any')

## S4 method for signature 'SpatExtent'
as.matrix(x, ...)

Arguments

x	SpatRaster or SpatVector
wide	logical. If FALSE each layer in the SpatRaster becomes a column in the matrix and each cell in the SpatRaster becomes a row. If TRUE each row in the SpatRaster becomes a row in the matrix and each column in the SpatRaster becomes a column in the matrix
mode	this argument is ignored
...	additional arguments (none implemented)

Value

vector, matrix, or array
