An S4 class to represent commodity import from the rest of the world.

Use newImport to create a new import object.

Details

Constructor for import object.

Import object adds an "external" source of commodity to the model. The RoW is not modeled explicitly as a region, export and import objects define and control the exchange with the RoW. The operation is similar to the demand object, but the two ideas distinguishes between internal and external final consumption. This exchange can be exogenously defined (imp.fx) or optimized by the model within the given limits (imp.lo, imp.up). The price column is used to define the price of the imported commodity. "Reserve" sets the total amount that can be imported over the model horizon.
