This objective allows for min and max targets to be specified.
minmax_objective(name, target = NULL, arguments = NULL, multiplier = 1, enabled = TRUE, ..., min, max)
name |
name of the objective, should correspond to a function, though we will try to make allowances |
target |

If target is set, we'll try to meet the metric
If target is NULL and min and max are specified, then do the following:
If max is violated to the upside, penalize the metric. If min is violated to the downside, penalize the metric. The purpose of this objective is to try to meet the range between min and max
