Create a new stock-and-flow model

Initialize an empty stock-and-flow model of class sdbuildR_xmile. You can either create an empty stock-and-flow model or load a template from the model library.

Usage

xmile(name = NULL)

Arguments

name

Name of the template to load. If NULL, an empty stock-and-flow model will be created with default simulation parameters and a default header. If specified, the name should be one of "logistic_model", "SIR", "predator-prey", "Crielaard2022", "coffee_cup", "bank_account", "Lorenz", "Rossler", "vanderPol", "Duffing", "Chua", "spruce_budworm".

Value

Stock-and-flow model of class sdbuildR_xmile.
