matchNearestNeighbor {CornerstoneR} | R Documentation |
Match the nearest neighbor from a redirected Cornerstone Robject
dataset
(redirectDataset
) to corresponding selected predictor variables.
Predictor variables from both datasets are supposed to be numeric to apply the Euclidean
distance calculated by dist2
.
The function returns a dataset with the nearest neighbor to every observation, matched by
the predictor variables.
Available response, group, and auxiliary variables from the redirected datasets are passed
through, as well as, selected auxiliary variables.
The calculated distance is attached.
