terra (version 1.8-21)

wrap: 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 SpatRaster
wrap(x, proxy=FALSE)
# S4 method for SpatRasterDataset
wrap(x, proxy=FALSE)
# S4 method for SpatRasterCollection
wrap(x, proxy=FALSE)
# S4 method for SpatVector
wrap(x)
# S4 method for ANY
unwrap(x)

Value

wrap: Packed* object

unwrap: SpatVector, SpatRaster, SpatRasterCollection, SpatRasterDataset

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

Examples

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