qgis_nearestneighbouranalysis: QGIS algorithm - Nearest neighbour analysis

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

QGIS algorithm - Nearest neighbour analysis

Description

QGIS Algorithm provided by QGIS (native c++) Nearest neighbour analysis (native:nearestneighbouranalysis). This algorithm performs nearest neighbor analysis for a point layer. The output describes how the data are distributed (clustered, randomly or distributed). Output is generated as an HTML file with the computed statistical values.

Usage

qgis_nearestneighbouranalysis(
  INPUT = qgisprocess:::qgis_default_value(),
  OUTPUT_HTML_FILE = qgisprocess:::qgis_default_value(),
  ...,
  .complete_output = .complete_output_option(),
  .quiet = .quiet_option(),
  .messages = .message_option()
)

Arguments

INPUT	source - Input layer. Path to a vector layer.
OUTPUT_HTML_FILE	fileDestination - Nearest neighbour. Path for new file.
...	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.
