Arguments

PREDICTOR

raster - Predictor. Path to a raster layer.

POINTS

source - Points. Path to a vector layer.

ATTRIBUTE

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

REGRESSION

rasterDestination - Regression. Path for new raster layer.

RESIDUAL

vectorDestination - Residuals. Path for new vector layer.

RESAMPLING

enum of ("(0) Nearest Neighbour", "(1) Bilinear Interpolation", "(2) Bicubic Spline Interpolation", "(3) B-Spline Interpolation") - Resampling. Number of selected option, e.g. '1'. Comma separated list of options, e.g. '1,3'.

METHOD

enum of ("(0) Y = a + b * X (linear)", "(1) Y = a + b / X", "(2) Y = a / (b - X)", "(3) Y = a * X^b (power)", "(4) Y = a e^(b * X) (exponential)", "(5) Y = a + b * ln(X) (logarithmic)") - Regression Function. Number of selected option, e.g. '1'. Comma separated list of options, e.g. '1,3'.

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.
