#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>'.

Example with R 📦 #qgisprocess: https://r-spatial.github.io/qgisprocess/articles/qgisprocess.html#second-example

Just discovered: the FOSS4G 2023 talk on R packages {#qgisprocess} and {qgis} has been online for a while 🙃.

Access #QGIS processing algorithms from R. No need for a QGIS project = enhanced reproducibility! Includes powerful tools like GRASS GIS, SAGA, PCRaster, etc.
