correct.zscore.signs: Corrects the z-scores signs according to the metrics

Description

For some metrics a high z-score is good, while for others a low one is good. This function corrects for that so that a negative z-score is a poor score for every metric. It then sets all positive scores to zero.

  signs.col.name = "Sign",
  filename = NULL
)
