Usage

sagang_snowcover(
  T = qgisprocess:::qgis_default_value(),
  P = qgisprocess:::qgis_default_value(),
  DAYS = qgisprocess:::qgis_default_value(),
  MEAN = qgisprocess:::qgis_default_value(),
  MAXIMUM = qgisprocess:::qgis_default_value(),
  QUANTILE = qgisprocess:::qgis_default_value(),
  QUANT_VAL = qgisprocess:::qgis_default_value(),
  TIME = qgisprocess:::qgis_default_value(),
  MONTH = qgisprocess:::qgis_default_value(),
  ...,
  .complete_output = .complete_output_option(),
  .quiet = .quiet_option(),
  .messages = .message_option()
)

Arguments

T	multilayer - Mean Temperature. .
P	multilayer - Precipitation. .
DAYS	rasterDestination - Snow Cover Days. Path for new raster layer.
MEAN	rasterDestination - Average. Path for new raster layer.
MAXIMUM	rasterDestination - Maximum. Path for new raster layer.
QUANTILE	rasterDestination - Quantile. Path for new raster layer.
QUANT_VAL	number - Value. 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.
TIME	enum of ⁠("(0) Year", "(1) January - March", "(2) April - June", "(3) July - September", "(4) October - December", "(5) Single Month")⁠ - Time. Number of selected option, e.g. '1'. Comma separated list of options, e.g. '1,3'.
MONTH	enum of ⁠("(0) January", "(1) February", "(2) March", "(3) April", "(4) May", "(5) June", "(6) July", "(7) August", "(8) September", "(9) October", "(10) November", "(11) December")⁠ - Month. 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.
