Error when Running Predictive Tools in ALteryx

[Bryth]

Hello Team, 

I am getting this error when I run predictive tools in Alteryx. Sometimes I get an output in the browse tool. I am not sure why this keeps happening. This also happen when I run Regression tools.

Hi @Bryth , this is a know 'Fake Error' in some R tools. It is called this because it often happens when no actual issue has occurred and the output is correct, but this error is thrown anyway. You can read about other people's experience with it here:

For some people, editing the R code in the tool and adding 'gc()' to the end seems to resolve the error. This command is 'garbage collector' and is used to clean memory after the code has run, but as far as I can tell no-one knows why this sometimes resolves the error. Anyway, if your output looks correct, you can probably ignore the error.
