In prioritizr: Systematic Conservation Prioritization in R

Objective class

Description

This class is used to represent the objective function used in optimization. Only experts should use the fields and methods for this class directly.

Super class

ConservationModifier -> Objective

Public fields

has_targets

logical value indicating if the objective supports targets. Values indicate that (TRUE) targets must be specified, (NA) targets are optional, and (FALSE) must are not used at all.

has_weights

logical value indicating if the objective supports feature weights.

Methods

Public methods

• Objective$default_weights()

• Objective$apply()

• Objective$clone()

Inherited methods

• ConservationModifier$calculate()
• ConservationModifier$get_data()
• ConservationModifier$get_internal()
• ConservationModifier$print()
• ConservationModifier$repr()
• ConservationModifier$set_data()
• ConservationModifier$set_internal()
• ConservationModifier$show()

---

Objective$default_weights()

Usage

Objective$apply(x)

Arguments

x

optimization_problem() object.

Returns

Invisible TRUE.

---

Objective$clone()

The objects of this class are cloneable with this method.

Usage

Objective$clone(deep = FALSE)

Arguments

deep

Whether to make a deep clone.
