saga_configure {Rsagacmd}

Generates a custom saga_cmd configuration file

Description

Creates and edits a saga_cmd configuration file in order to change saga_cmd settings related to file caching and number of available processor cores. Intended to be used internally by saga_gis

Usage

saga_configure(
  senv,
  grid_caching = FALSE,
  grid_cache_threshold = 100,
  grid_cache_dir = NULL,
  cores = NULL,
  saga_vers
)

Arguments

senv

A saga environment object. Contains the SAGA-GIS environment and settings.

grid_caching

Whether to use file caching. The default is FALSE.

grid_cache_threshold

Any number to use as a threshold (in Mb) before file caching for loaded raster data is activated.

grid_cache_dir

Optionally specify a path to the used directory for temporary files. The default uses 'base::tempdir'.

cores

An integer specifying the maximum number of processing cores. Needs to be set to 1 if file caching is activated because file caching in SAGA-GIS is not thread-safe.

saga_vers

A 'numeric_version' that specifies the version of SAGA-GIS. The generation of a saga_cmd configuration file is only valid for versions > 4.0.0.

Value

A character that specifies the path to custom saga_cmd initiation file.
