Coercion to vector, matrix or array

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

Usage

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

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

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

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

# S4 method for class '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
