Examples

# not running below examples in R CMD check to save time
result <- qgis_run_algorithm(
  "native:slope",
  INPUT = system.file("longlake/longlake_depth.tif", package = "qgisprocess")
)

# most direct approach, autoselecting a `qgis_outputRaster` type
# output from the `result` object and reading as RasterLayer:
qgis_as_raster(result)

# if you need more control, extract the needed output element first:
output_raster <- qgis_extract_output(result, "OUTPUT")
qgis_as_raster(output_raster)
