tnss_dummies: Sample points for triangulated networks

In schochastics/edgebundle: Algorithms for Bundling Edges in Networks and Visualizing Flow and Metro Maps

Sample points for triangulated networks

Description

uses various sampling strategies to create dummy nodes for the tnss_tree

Usage

tnss_dummies(
  xy,
  root,
  circ = TRUE,
  line = TRUE,
  diag = TRUE,
  grid = FALSE,
  rand = FALSE,
  ncirc = 9,
  rcirc = 2,
  nline = 10,
  ndiag = 50,
  ngrid = 50,
  nrand = 50
)

Arguments

xy	coordinates of "real" nodes
root	root node id
circ	logical. create circular dummy nodes around leafs.
line	logical. create dummy nodes on a straight line between root and leafs.
diag	logical. create dummy nodes diagonally through space.
grid	logical. create dummy nodes on a grid.
rand	logical. create random dummy nodes.
ncirc	numeric. number of circular dummy nodes per leaf.
rcirc	numeric. radius of circles around leaf nodes.
nline	numeric. number of straight line nodes per leaf.
ndiag	numeric. number of dummy nodes on diagonals.
ngrid	numeric. number of dummy nodes per dim on grid.
nrand	numeric. number of random nodes to create.

Value

coordinates of dummy nodes

# dummy nodes for tree rooted in California
xy <- cbind(state.center$x, state.center$y)
xy_dummy <- tnss_dummies(xy, 4)
