Details

The following options are available.

memfrac - value between 0 and 0.9 (larger values give a warning). The fraction of RAM that may be used by the program.

memmax - the maximum amount of RAM (in GB) that terra can use when processing a raster dataset. Should be less than what is detected (see mem_info, and higher values are ignored. Set it to a negative number or NA to not set this option). terraOptions only shows the value of memmax it it set.

tempdir - directory where temporary files are written. The default what is returned by tempdir().

datatype - default data type. See writeRaster

todisk - logical. If TRUE write all raster data to disk (temp file if no file name is specified). For debugging.

progress - non-negative integer. A progress bar is shown if the number of chunks in which the data is processed is larger than this number. No progress bar is shown if the value is zero

verbose - logical. If TRUE debugging info is printed for some functions

# NOT RUN {
terraOptions()
terraOptions(memfrac=0.5, tempdir = "c:/temp")
terraOptions(progress=10)
