RStudio and neuralnets gwplot does not work #28

Open Oakwilde opened 5 years ago

Oakwilde commented 5 years ago

It works fine in R by itself

mnwright commented 5 years ago

Works here. Could you give a reproducible example?

Oakwilde commented 5 years ago

Here is an example. Thanks.

Richard

It works after I scaled all of the predictors. What is strange is that I got weights when I did not scale but no generalized weights. Am I missing something in the documentation?

Thanks.

It seems to be a random issue related to convergence. Might it be that the network didn't converge in the cases where gwplot() did not work? On scaled data it should converge faster, so it would make sense in your case.

Oakwilde commented 5 years ago

Thanks. Yes, that could be it, but I got weights and was able plot the visual of the network. There was also no error message that convergence failed (which I have gotten for other applications).
