add_proportion_decisions: Add Proportion Decisions

Description

Add a proportion decision to a conservation planning problem. This is a relaxed decision where a part of a planning unit can be prioritized as opposed to the entire planning unit. Typically, this decision has the assumed action of buying a fraction of a planning unit to include in

Usage

add_proportion_decisions(x)

Arguments

x

ConservationProblem-class object.

Value

Decision-class object.

Details

Conservation planning problems involve making decisions on planning units. These decisions are then associated with actions (e.g. turning a planning unit into a protected area). If no decision is explicitly added to a problem, then the binary decision class will be used by default. Only a single decision should be added to a ConservationProblem object. If multiple decisions are added to a problem object, then the last one to be added will be used.

# NOT RUN {
# create problem with proportion decisions

# }
# NOT RUN {
# solve problem
s <- solve(p)

# plot solutions
plot(s, main = "solution", axes = FALSE, box = FALSE)
