Decision Tree Error

Highlighted

Hey,

I am running a normal decision tree model on some data and getting the following error:

 

'Decision Tree: Alteryx R integration does not support unicode character outside of string constants'

 

Does anyone know what it means and what is the solution?

 

Thank You

@Ysamuel It looks like the data you are using at this point may contain unsupported characters to run in R. I would suggest looking at the Data Investigation tools to see what issues your data may have and then use the other tools to resolve those issues. R is very specific on the data it can accept, that is why we highly recommend cleaning and prepping data before using the predictive tools. Here also is the link to the Decision Tree help which has further information.

For me this was variable names it didn't like. I renamed them with a select and it worked after that.
