serialize {terra}

saveRDS and serialize for SpatVector and SpatRaster*

Description

serialize and saveRDS for SpatVector, SpatRaster, SpatRasterDataset and SpatRasterCollection. Note that these objects will first be "packed" with wrap, and after unserialize/readRDS they need to be unpacked with rast or vect.

Extensive use of these functions is not recommended. Especially for SpatRaster it is generally much more efficient to use writeRaster and write, e.g., a GTiff file.

Usage

## S4 method for signature 'SpatRaster'
saveRDS(object, file="", ascii = FALSE, version = NULL, compress=TRUE, refhook = NULL)

## S4 method for signature 'SpatRasterDataset'
saveRDS(object, file="", ascii = FALSE, version = NULL, compress=TRUE, refhook = NULL)

## S4 method for signature 'SpatRasterCollection'
saveRDS(object, file="", ascii = FALSE, version = NULL, compress=TRUE, refhook = NULL)

## S4 method for signature 'SpatVector'
saveRDS(object, file="", ascii = FALSE, version = NULL, compress=TRUE, refhook = NULL)

## S4 method for signature 'SpatRaster'
serialize(object, connection, ascii = FALSE, xdr = TRUE, version = NULL, refhook = NULL)

## S4 method for signature 'SpatVector'
serialize(object, connection, ascii = FALSE, xdr = TRUE, version = NULL, refhook = NULL)
