Use QGIS Processing Algorithms
Provides seamless access to the QGIS (<https://qgis.org>) processing toolbox using the standalone qgis_process command-line utility. Both native and third-party (plugin) processing providers are supported. Beside referring data sources from file, also common objects from sf, terra and stars are supported. The native processing algorithms are documented by QGIS.org (2024) <https://docs.qgis.org/latest/en/docs/user_manual/processing_algs/>.
In preparation of #useR2024 π¦ #qgisprocess 0.4.0 was released on CRAN last week:
π faster loading and less overhead
π new vignette about passing R objects to #QGIS processing algorithms
π new vignette about package settings

Announcing that users of the package are welcome to cite their work on the homepage of {qgisprocess}. Users can be direct users or qgis users. These references will be added under subsection 'In th...
#GRASSGIS algorithms used to be named as 'grass7:<algorithm>' in #QGIS. But they also work with GRASS GIS 8!
Since QGIS 3.36 the provider is named... 'grass' ! Just use the algorithm syntax 'grass:<algorithm>'.

Convert networkx graph to qgsvectorlayer in pyqgis
I'm converting to a QGIS processing plugin a python script that loads two spatial layers (nodes and edges), converts them to a graph using networkx and after doing some transformation converts back...
Just discovered: the FOSS4G 2023 talk on R packages {#qgisprocess} and {qgis} has been online for a while π.
Access #QGIS processing algorithms from R. No need for a QGIS project = enhanced reproducibility! Includes powerful tools like GRASS GIS, SAGA, PCRaster, etc.
