Arguments

POINTS

source - Points. Path to a vector layer.

FIELD

field - Attribute. The name of an existing field. ; delimited list of existing field names.

FILTER

vectorDestination - Filtered Points. Path for new vector layer.

RADIUS

number - Radius. 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.

MINNUM

number - Minimum Number of 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.

MAXNUM

number - Maximum Number of 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.

QUADRANTS

boolean - Quadrants. 1 for true/yes. 0 for false/no. 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.

METHOD

enum of ("(0) keep maxima (with tolerance)", "(1) keep minima (with tolerance)", "(2) remove maxima (with tolerance)", "(3) remove minima (with tolerance)", "(4) remove below percentile", "(5) remove above percentile") - Filter Criterion. Number of selected option, e.g. '1'. Comma separated list of options, e.g. '1,3'.

TOLERANCE

number - Tolerance. 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.

PERCENT

number - Percentile. 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.

...

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.
