The partition layout is a way to show hierarchical data in the same way as
layout_tbl_graph_treemap(). Instead of subdividing the parent area
the partition layout shows the division of a nodes children next to the area
of the node itself. As such the node positions will be very reminiscent of
a reingold-tilford tree layout but by plotting nodes as areas it better
communicate the total weight of a node by summing up all its children.
Often partition layouts are called icicle plots or sunburst diagrams (in case
a radial transform is applied).
layout_tbl_graph_partition(
graph,
weight = NULL,
circular = FALSE,
height = NULL,
sort.by = NULL,
direction = "out",
offset = pi/2,
const.area = TRUE
)If circular = FALSE A data.frame with the columns x,
y, width, height, leaf,
depth, circular as well as any information stored as node
variables in the tbl_graph object.
If circular = TRUE A data.frame with the columns x, y,
r0, r, start, end, leaf,
depth, circular as well as any information stored as node
variables in the tbl_graph object.
An tbl_graph object
An optional node variable to use as weight. Will only affect the weight of leaf nodes as the weight of non-leaf nodes are derived from their children.
Logical. Should the layout be transformed to a circular
representation. If TRUE the resulting layout will be a sunburst
diagram.
An optional node variable to use as height. If NULL
all nodes will be given a height of 1.
The name of a node variable to sort the nodes by.
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.
If circular = TRUE, where should it begin. Defaults to
pi/2 which is equivalent to 12 o'clock.
Logical. Should 'height' be scaled for area proportionality
when using circular = TRUE. Defaults to TRUE.
