Description
Hi,
I am not able to find the R^2 value (coefficient of determination) for regression tasks in the result table. I see a lot of regression evaluation criteria but R^2 seems to be missing. When using specific definitions of R2 it is simply the square of the correlation coefficient (which exists on openml.org) but, unfortunately, this is not the case for the definition used in scikit-learn (which, in turn, is used in many frameworks such as AutoML Benchmark).
Does it really not exist? If so, what is the reason behind this and do you know of a workaround? Thanks in advance!

Research direction
Start by locating the result table and the regression evaluation criteria it displays. Compare the available metrics with scikit-learn's R² definition, then determine whether the requested value can be exposed there and verify that the table clearly reports it when complete.
