Multiple regression analysis chart from Advance Analytics Extension not working

[rohitk1609]

Hi team,

I am exploring Advance Analytics extension which works on Microsoft R.  I have taken very simple data which has order date, sales, sales quantity and product name.

Linear regression chart is working fine but Multiple regression analysis is not working:

I have selected Order Date in Dimension, Add measure-Response variable= Sales and Add measure - Predictor variable.

but it is returning error

This is log message in RServe.exe

I have installed all the packages mentioned in https://github.com/mhamano/advanced-analytics-toolbox/blob/master/docs/packages.md.

Can anyone please help me to know what exactly I am missing?

Thanks in advance
