E.g. '4,10,101,105' - Path to a layer. The extent of the layer is used. TARGET_USER_SIZE: Cellsize Default value: 100 Argument type: number Acceptable values: - 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 TARGET_OUT_GRID: Target Grid Argument type: rasterDestination Acceptable values: - Path for new raster layer

)

Arguments

POINTS	source - Points. Path to a vector layer.
FIELD	field - Attribute. The name of an existing field. ; delimited list of existing field names.
CV_METHOD	enum of ⁠("(0) none", "(1) leave one out", "(2) 2-fold", "(3) k-fold")⁠ - Cross Validation. Number of selected option, e.g. '1'. Comma separated list of options, e.g. '1,3'.
CV_SUMMARY	vectorDestination - Cross Validation Summary. Path for new vector layer.
CV_RESIDUALS	vectorDestination - Cross Validation Residuals. Path for new vector layer.
CV_SAMPLES	number - Cross Validation Subsamples. 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.
TARGET_USER_XMIN_TARGET_USER_XMAX_TARGET_USER_YMIN_TARGET_USER_YMAX	extent - Output extent. A comma delimited string of x min, x max, y min, y max. E.g. '4,10,101,105'. Path to a layer. The extent of the layer is used.. Original algorithm parameter name: TARGET_USER_XMIN TARGET_USER_XMAX TARGET_USER_YMIN TARGET_USER_YMAX.
TARGET_USER_SIZE	number - Cellsize. 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.
TARGET_OUT_GRID	rasterDestination - Target Grid. Path for new raster 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.
