"Linear Regression: squared correlation missing from performance criterion select"

I have a feeling this is 1 of those questions blindingly obvious to everyone but me (very new to this field) but I'm hoping someone can help me out.

I have RapidMiner 5.3.015 process which has a numerical cross validation block to get the performance measures for linear regression. The process runs and outputs the model, training data and the following performance vectors
  • root_mean_squared_error
but no squared correlation

How do I add that to the performance output as I can't see any parameters on the performance block or validation

    I was using the wrong performance measure needed to use the performance (regression) operator
