Generate network based on coordinates.

Description

Create a (clustered) network object.

Usage

makeNetwork(
  coordinates,
  distance.matrix = NULL,
  name = NULL,
  comment = NULL,
  membership = NULL,
  edge.weight.type = NULL,
  depot.coordinates = NULL,
  lower = NULL,
  upper = NULL,
  opt.tour.length = NULL,
  opt.tour = NULL,
  node.weights = NULL
)

Arguments

`coordinates`	[`matrix`] Numeric matrix of 2D coordinates.
`distance.matrix`	[`matrix`] Optional distance matrix.
`name`	[`character(1)` \| `NULL`] Optional name of the network.
`comment`	[`character` \| `NULL`] Optional additional comments on instance.
`membership`	[`numeric` \| `NULL`] Optional vector of memberships for clustered networks.
`edge.weight.type`	[`character(1)` \| `NULL`] The edge weight type indicates how edge weights are represented in the TSPlib format. If `distance.matrix` is `NULL`, the passed value is ignored and EUC_2D is assigned. Otherwise the edge weight type must be one of the following `{EUC_2D, EUC_3D, MAX_2D, MAX_3D, MAN_2D, MAN_3D, CEIL_2D, GEO, ATT, EXPLICIT}`.
`depot.coordinates`	[`matrix` \| `NULL`] Numeric matrix of 2D coordinates of depots. Default is `NULL`, which means no depots at all.
`lower`	[`numeric(1)`] Lower box constraint of cube.
`upper`	[`numeric(1)`] Upper box constraint of cube.
`opt.tour.length`	[`numeric(1)`] Optional length of the optimal roundtrip tour. Default is `NULL`, which means the tour length is unknown.
`opt.tour`	[`integer`] Optional optimal permutation of node indizes. Default is `NULL`, which means the optimal tour is unknown.
`node.weights`	[`numeric`] Vector of node weights (for weighted version of TSP). Default is `NULL`, i.e., no node weights at all.
