[! DEPRECATED] Find indices of rows that contain outlier column-wise outliersscores

[! DEPRECATED] Return indices of rows in scores matrix that contain outliers. A row is treated as having an oultier if any autoscaled score in that row is not between 1 zLimit.

whichOutlier(x, zLimit = 2)

Arguments

x

Matrix-like data.

zLimit

A threshold for standardized (scaled) values (i.e., z-scores) to be treated as an outlier. If (-zLimit) < scale(scores) or scale(scores) > (+zLimit) it is treated as an outlier.
Default zLimit = 2.

Value

Vector of indices that indicate rows containing outliers.
