result from tdmRegressLoop and add result$y.result$y is "OOB RMAE" on training set for methods RF or MC.RF.
result$y is "RMAE" on test set (=validation set) for all other methods.
result$y is the quantity which the tuner seeks to minimize.
tdmRegressSummary(result, opts, dset = NULL)return value from a prior call to tdmRegressLoop, an object of class TDMregressor.
a list from which we need here the following entries
NRUNnumber of runs (outer loop)
methodVERBOSEdset[NULL] if !=NULL, attach it to result
[NULL] if not NULL, add this data frame to the return value (may cost a lot of memory!)
result, an object of class TDMregressor, with result$y, result$sd.y
(and optionally also result$dset) added
