Details

In many methods, options for writing raster files to disk can be provided with the wopt argument. wopt should be a named list. The following options are available:

name	description
`filetype`	file format expresses as GDAL driver names. If this argument is not supplied, the driver is derived from the filename.
`datatype`	values for `datatype` are "INT1U", "INT2U", "INT2S", "INT4U", "INT4S", "FLT4S", "FLT8S". The first three letters indicate whether the datatype is integer (whole numbers) of a real number (decimal numbers), the fourth character indicates the number of bytes used (allowing for large numbers and/or more precision), and the "S" or "U" indicate whether the values are signed (both negative and positive) or unsigned (postive values only).
`gdal`	GDAL driver specific datasource creation options. See the GDAL documentation. For example: `gdal=c("COMPRESS=LZW", "TFW=YES")`
`tempdir`	the path where temporary files are to be written to
`progress`	postive integer. If the number of chunks is larger, a progress bar is shown
`memfrac`	numeric between 0.1 and 0.9. The fraction of available RAM that terra is allowed to use
`names`	output layer names
`NAflag`	numeric. code to use for NA values
`verbose`	logical. If `TRUE` debugging information is printed
`todisk`	logical. If `TRUE` processing operates as if the dataset is very large and needs to be written to a temporary file (for debugging)
