layout_tbl_graph_htree: Layout binary trees in a fractal H formation

In ggraph: An Implementation of Grammar of Graphics for Graphs and Networks

Layout binary trees in a fractal H formation

Description

This is a spac efficient layout only useful for binary trees. It is fractal and works by offsetting child nodes from their parent either horizontally or vertically depending on depth. The offset is decreased at each step by a factor of the square root of 2.

Usage

layout_tbl_graph_htree(
  graph,
  sort.by = NULL,
  direction = "out",
  circular = FALSE
)

Arguments

graph	An tbl_graph object
sort.by	The name of a node variable to sort the nodes by.
direction	The direction of the tree in the graph. 'out' (default) means that parents point towards their children, while 'in' means that children point towards their parent.
circular	Logical. Should the layout be transformed to a circular representation. Ignored

Value

A data.frame with the columns x, y, leaf, depth, circular as well as any information stored as node variables in the tbl_graph object.

Note

H Tree is a layout intended for trees, that is, graphs where nodes only have one parent and zero or more children. If the provided graph does not fit this format an attempt to convert it to such a format will be made.
