Run QGIS algorithms. See the QGIS docs for a detailed description of the algorithms provided 'out of the box' on QGIS (versions >= 3.14).
qgis_has_algorithm(algorithm)
qgis_algorithms(query = FALSE, quiet = TRUE)
qgis_has_provider(provider, query = FALSE, quiet = TRUE)
qgis_providers(provider)
assert_qgis_algorithm(algorithm)A qualified algorithm name (e.g., "native:filedownloader") or a path to a QGIS model file.
Use TRUE to refresh the cached value.
Use TRUE to suppress output from processing algorithms.
A provider identifier (e.g., "native")
