qgis_distancematrix: QGIS algorithm - Distance matrix

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

QGIS algorithm - Distance matrix

Description

QGIS Algorithm provided by QGIS Distance matrix (qgis:distancematrix). This algorithm creates a table containing a distance matrix, with distances between all the points in a points layer.

Usage

qgis_distancematrix(
  INPUT = qgisprocess:::qgis_default_value(),
  INPUT_FIELD = qgisprocess:::qgis_default_value(),
  TARGET = qgisprocess:::qgis_default_value(),
  TARGET_FIELD = qgisprocess:::qgis_default_value(),
  MATRIX_TYPE = qgisprocess:::qgis_default_value(),
  NEAREST_POINTS = qgisprocess:::qgis_default_value(),
  OUTPUT = qgisprocess:::qgis_default_value(),
  ...,
  .complete_output = .complete_output_option(),
  .quiet = .quiet_option(),
  .messages = .message_option()
)

Arguments

INPUT	source - Input point layer. Path to a vector layer.
INPUT_FIELD	field - Input unique ID field. The name of an existing field. ; delimited list of existing field names.
TARGET	source - Target point layer. Path to a vector layer.
TARGET_FIELD	field - Target unique ID field. The name of an existing field. ; delimited list of existing field names.
MATRIX_TYPE	enum of ⁠("Linear (N*k x 3) distance matrix", "Standard (N x T) distance matrix", "Summary distance matrix (mean, std. dev., min, max)")⁠ - Output matrix type. Number of selected option, e.g. '1'. Comma separated list of options, e.g. '1,3'.
NEAREST_POINTS	number - Use only the nearest (k) target points. A numeric value. field:FIELD_NAME to use a data defined value taken from the FIELD_NAME field. expression:SOME EXPRESSION to use a data defined value calculated using a custom QGIS expression.
OUTPUT	sink - Distance matrix. 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.
