[Windows SO][Bug?] Detect R folder about qgis-processing-r

[PedroVenancio]

@jonnyforestGIS
The problem is fixed here, with the release 0.0.3.

[nyalldawson]

@jonnyforestGIS

I suspect an installation issue there. Try this version -- it will work using the "install plugin from zip" option from the plugins dialog:

r.zip

[nyalldawson]

@jonnyforestGIS

When it's done and you try to run an algorithm, you should see a line like this in the message log panel:

[jonnyforestGIS]

Ok @nyalldawson and @PedroVenancio. I will try and give you feedback tomorrow and if everything go right i close this issue. Thank you for your time.

[nyalldawson]

Can you test with current master version? This should output some debug text to the log panel, under the R tab when you attempt to run an algorithm. It will give the current determined path for the R executable.

[jonnyforestGIS]

Steps.

1. Erase the default profile.
2. Don't import settings from 2.x
3. Copy and past in the QGIS plugins the r processing plugin master folder.
4. Run QGIS 3.4.1. Activate the R (assume correctly the path of R in processing settings providers) My case: C:\Program Files\R\R-3.2.0
5. Run the test script and give me same behavior (Can't find R).

Don't appear nothing in the python warnings or processing log viewer or processing results.
I'm doing something wrong?

[jonnyforestGIS]

[UPDATE]
After i close and open the QGIS. This errors star int he python warnings.

[nyalldawson]

Thanks @jonnyforestGIS -- I'm keen to get this stable, as these binary paths were a persistently annoying issue with the old 2.x version of the provider.

[jonnyforestGIS]

Hi 👍 it's working. @nyalldawson I will close this issue. What are the next steps for this provider? Do you intend to put the same features as qgis 2.x? For example Right click to see and change the code for example?

[nyalldawson]

@jonnyforestGIS you should already be able to edit existing scripts via right click.

The current roadmap is basically outlined via the open tickets here. There's a handful of remain parts to implement still.

[jonnyforestGIS]

I confirm @nyalldawson .
I just test a sample code of R Histogram equal to QGIS 2.x but give me an error on QGIS 3.x. I will open a new issue with this subject.
Feel free to notify me for extra tests in Windows Environment. Good work.
