Cannot run grass commands using R

[jfsmenezes]

Hi,

I am having an issue where I can run QGIS and SAGA algorithms in RQGIS3 but I receive python erros when running GRASS commands. for example:

  set_env("C:\\Program Files\\QGIS 3.10")
  run_qgis("qgis:createconstantrasterlayer", EXTENT = "-10,10,-10,10", OUTPUT="test.tif")  
  #outputs file path, as expected.
  run_qgis("grass7:i.fft",input="test.tif",
                    real="test2.tif",
                    imaginary="test3.tif"
                    )
 #Error in py_call_impl(callable, dots$args, dots$keywords): 
 #QgsProcessingException: There were errors executing the algorithm.

 #Detailed traceback:
 #File "C:/Program Files/QGIS 3.10/apps/qgis/python/plugins\processing\tools\general.py", line 
 #106, in run
 #return Processing.runAlgorithm(algOrName, parameters, 
 #onFinish, feedback, context)
 #File "C:/Program Files/QGIS 3.10/apps/qgis/python/plugins\processing\core\Processing.py", 
 #line 181, in runAlgorithm
 #raise QgsProcessingException(msg)

Does anyone know how can I fix that?

This problem does not seems to happen in another computer with QGIS 3.4. So maybe it is related to the qgis version?

By the way I would like to thanks the package authors. This is a very easy to use package and really speed up my GIS analysis on R.

Thanks! We currently have not much time for this package.

QGIS changes a lot in new releases and it can very well be that it is related to a new version. We do not have a working CI integration which reliably checks the functions against the latest QGIS version. So fingers crossed and we suggest to stick to a working environment once you have found one 😅

Thanks! We currently have not much time for this package.

Which QGIS version is the latest one that is supported or works for you?

I have the same problem, it is a last listen that improvements to the package are not heard, which is very good.

I don't know what you mean.

Everyone is welcome to contribute and fix things. This package is a FOSS offer, not a paid service.
