Problem with `keepModel` option in `evaluationScheme.evaluate()` method #54

Closed gregreich closed 3 years ago

gregreich commented 3 years ago

It would be great if the RECOMs are stored when evaluated via evaluationScheme, for example to record the outcome of an AR mining process, etc. My understanding is that evaluate(..., keepModel = TRUE) would allow this; but it gives me an error:

AR run fold/sample [model time/prediction time]
...

  unable to find an inherited method for function ‘getModel’ for signature ‘"numeric"’

This looks like a bug. I will look into it.

This should now be fixed.

Thank you! Works as expected now.
