In terra: Spatial Data Analysis

wrap and unwrap

Description

Use wrap to pack a SpatVector or SpatRaster* to create a Packed* object. Packed objects can be passed over a connection that serializes (e.g. to nodes on a computer cluster). At the receiving end they need to be unpacked with unwrap.

Usage

## S4 method for signature 'SpatRaster'
wrap(x, proxy=FALSE)

## S4 method for signature 'SpatRasterDataset'
wrap(x, proxy=FALSE)

## S4 method for signature 'SpatRasterCollection'
wrap(x, proxy=FALSE)

## S4 method for signature 'SpatVector'
wrap(x)

## S4 method for signature 'ANY'
unwrap(x)

Arguments

x	SpatVector, SpatRaster, SpatRasterDataset or SpatRasterCollection
proxy	logical. If FALSE raster cell values are forced to memory if possible. If TRUE, a reference to source filenames is stored for data sources that are not in memory

Value

wrap: Packed* object

unwrap: SpatVector, SpatRaster, SpatRasterCollection, SpatRasterDataset

Examples

f <- system.file("ex/lux.shp", package="terra")
v <- vect(f)
p <- wrap(v)
p
vv <- vect(p)
vv
