sagang_leastcostpaths: QGIS algorithm - Least cost paths

In JanCaha/r_package_qgis: An extension of package "qgisprocess" providing direct R functions for QGIS functions

QGIS algorithm - Least cost paths

Description

QGIS Algorithm provided by SAGA Next Gen Least cost paths (sagang:leastcostpaths). —————- Arguments —————- SOURCE: Source Point(s) Argument type: source Acceptable values: - Path to a vector layer DEM: Accumulated Cost Surface Argument type: raster Acceptable values: - Path to a raster layer VALUES: Values (optional) Argument type: multilayer POINTS: Profile Points Argument type: vectorDestination Acceptable values: - Path for new vector layer LINE: Profile Lines Argument type: vectorDestination Acceptable values: - Path for new vector layer

Usage

sagang_leastcostpaths(
  SOURCE = qgisprocess:::qgis_default_value(),
  DEM = qgisprocess:::qgis_default_value(),
  VALUES = qgisprocess:::qgis_default_value(),
  POINTS = qgisprocess:::qgis_default_value(),
  LINE = qgisprocess:::qgis_default_value(),
  ...,
  .complete_output = .complete_output_option(),
  .quiet = .quiet_option(),
  .messages = .message_option()
)

Arguments

SOURCE	source - Source Point(s). Path to a vector layer.
DEM	raster - Accumulated Cost Surface. Path to a raster layer.
VALUES	multilayer - Values. .
POINTS	vectorDestination - Profile Points. Path for new vector layer.
LINE	vectorDestination - Profile Lines. Path for new vector layer.
...	further parameters passed to qgisprocess::qgis_run_algorithm()
.complete_output	logical specifying if complete out of qgisprocess::qgis_run_algorithm() should be used (TRUE) or first output (most likely the main) should read (FALSE). Default value is TRUE.
.quiet	logical specifying if parameter .quiet for qgisprocess::qgis_run_algorithm() Default value is TRUE.
.messages	logical specifying if messages from qgisprocess::qgis_run_algorithm() should be printed (TRUE) or not (FALSE). Default value is FALSE.
