Parcels_Create manually creates the problem's data. It
will create variables named
Parcels storing the name of parcels and the order they are used, and
Status showing whether parcels are protected or not.
Note: These variables are essential to create the optimization problem. So, if not created, calling other functions will result in an error.
A vector of strings: the name of the parcels appearing in the problem
A vector of binary: the respective status of the parcels in
A binary parameter: if
the environment where the package should create or access variables. By default the package works in the R's Global environment. (Default: .GlobalEnv)
Parcels should include the name of all parcels appearing in the problem,
Status should include all the parcels' status, where value
1 means the parcel is protected (owned), and value 0 means the
parcel is unprotected (unowned). These values are essential in creating
In the optimization model, protected (owned) and unprotected (unowned) parcels
will be represented by the binary decision variables
x. In the final solution after optimization,
(1-y)=1 means that
the parcel which was initially protected (owned) remains protected, and
(1-y)=0 means that the parcel is divested (sold).
that the parcel that was initially unprotected (unowned) will become protected (invested), and
x=0 means that the parcel will remain unprotected.

NULL (creates some variables in the environment but returns nothing)
