I have been trying to implement a workflow using "R Linear Regression" but has been showing errors,

I performed steps of cleaning the data by :

removing nulls

changing data types

The columns I am trying to predict are set as "double".

Hello @jkalal

Without seeing the data I'm not sure what could be causing this. My initial thought would be that one of your data columns going into the model contains non-Unicode characters. One wat to try and fix this is to just remove all non-Unicode characters. You could do this using the following regex  REGEX_Replace([Name], '[^ -~]', ''). It works by looking at the list of ascii characters between a space and a ~. This contains most common letters, numbers and special characters. Anything not in this range is simply removed. I would try applying this to the columns that you feed into your model.

Please let me know how you got on.
