qgis_algorithms function

List algorithms, processing providers or plugins

Functions that return metadata about the installed and enabled algorithms or processing providers, or about the installed plugins that implement processing providers. See the QGIS docs

for a detailed description of the algorithms provided 'out of the box' on QGIS.

qgis_algorithms(query = FALSE, quiet = TRUE, include_deprecated = TRUE)

qgis_providers(query = FALSE, quiet = TRUE, include_deprecated = TRUE)

qgis_plugins(which = "all", query = FALSE, quiet = TRUE, ...)

Arguments

• query: Use TRUE to refresh the cached value.
• quiet: Use FALSE to display more information, possibly useful for debugging.
• include_deprecated: Logical. Should deprecated algorithms be included?
• which: String defining which plugins to select, based on their status in QGIS (enabled or disabled). Must be one of: "all", "enabled", "disabled".
• ...: Only used by other functions calling this function.

Returns

A tibble of algorithms, processing providers or plugins, with metadata.

Details

The include_deprecated argument in qgis_algorithms() does not affect the cached value. The latter always includes deprecated algorithms if these are returned by 'qgis_process' (this requires the JSON output method).

Examples

qgis_algorithms()
qgis_algorithms(include_deprecated = FALSE)
qgis_providers()
qgis_plugins(quiet = FALSE)
qgis_plugins(which = "disabled")
