Tool: Model Comparison

[JHFongSF87]

When I am running the workflow for the Model Comparison macro, this error shows up "Error in plot.new()". This is when I am initializing the macro. Due to this when I run the model comparison tool, the Confusion Matrix Section of the report is missing. Anyone know how to fix this? I am currently enrolled in Udacity's Predictive Analytics for Business Analysts if that provides context.

Loading in the macro from Predictive District:

Running a Decision Tree and validating model with 70/30 split:

Can you attach the workflow that you are attempting to run (as a package so that the data is included)?

Also, note the following passage in the tool description on the tool's Gallery page...

To use this macro, and additional R packages (ROCR) needs to be installed. The link below provides instructions on how to install R packages that can be accessed by Alteryx. The macro will attempt to install the needed R packages if they are not already installed, but this may be prevented by certain firewalls and proxy servers.

So try installing the ROCR package with this app: https://gallery.alteryx.com/#!app/Install-R-Packages/57bb2a58a248970b4472c2e6

Thanks Neil,

I have tried to install additonal R packages, but the same error still appears with this data set.

The workflow you sent runs fine on my machine, so it's like something to do with your setup. I'd recommend reaching out to Alteryx Support and they can take a closer look at your setup.

Thanks, @NeilR!   @JHFongSF87, the workflow runs correctly on my machine, as well.  Were you able to get any additional information from Showing Macro Messages?

[JHFongSF87]

Thanks for the confirmation, I will maybe try and do a reinstall to see if that works correctly.

After reloading and importing the macro, it appears the problem seems to be in the set up of the macro itself and not necessarily the data set. I have loaded the macro with images to see if you could possible understand it. This macro was taken from the predictive gallery.

Hi @JHFongSF87, are you getting that error from the macro in your workflow, or when you open the macro and run it as-is?  Can you go into your Workflow-Configuration> Runtime tab, click to "Show all macro messages," and send the full error message?

Thanks!

[JHFongSF87]

@CristonS, the error comes from when I run the workflow once it is imported. Due to the fact it is a .yxmc file, I can't find the Runtime option in the Workflow Configuration like the other file which was a .yxmd.

Steps are as follows: 

 

Loaded the macro with no errors but then once it is on my screen in the workflow I run the workflow. I am currently using a Virtual PC, VMWare Fusion, would this cause an issue with the macro?
