wrapCache function

SpatRaster wrap with caching options

Use wrap to pack a SpatRaster with caching options. See wrap for the general approach that is easier and better to use in most cases.

This method allows for specifying a folder, or filenames, to cache all sources of a SpatRaster in a specific location (on disk).

## S4 method for signature 'SpatRaster'
wrapCache(x, filename=NULL, path=NULL, overwrite=FALSE, ...)

Arguments

• x: SpatRaster
• filename: character. A single filename, or one filename per SpatRaster data source. If not NULL, the raster sources are saved in these files
• path: character. If not NULL, the path where raster sources will be saved. Ignored if filenames is not NULL
• overwrite: Should existing files be overwritten when files or path is not NULL? If this value is not TRUE or FALSE, only files that do not exist are created
• ...: Additional arguments for writeRaster. Only used for raster sources that are in memory, as other sources are cached by copying the files

Returns

PackedSpatRaster
