Create a graph from a model specification

Convert a model specification into a graph (using the graph package) that can be plotted with Rgraphviz: see ?Rgraphviz::plot.graphNEL and https://graphviz.org/doc/info/attrs.html for information on customizing the plot.

Usage

dot_layout(spec, include_inout = FALSE)

Arguments

spec: a model specification
include_inout: (logical) include nodes defined by mp_per_capita_inflow and mp_per_capita_outflow ?

Details

In order to plot the graph, you need to have loaded the Rgraphviz package (library("Rgraphviz")).

Examples

if (require(Rgraphviz)) {
  macpan_base = mp_tmb_library("starter_models", "macpan_base", package = "macpan2")
  ## plot with left-to-right layout, rectangles instead of default circles
  dot_layout(macpan_base) |>
    plot(attrs = list(graph = list(rankdir = "LR"),
                      node = list(shape = "rectangle")))
}
