edgebundleR (version 0.1.4)

edgebundle: Circle plot with bundled edges

Description

Takes an appropriately structured JSON file or a square symmetric matrix (e.g. a correlation matrix or precision matrix) and outputs a circle plot with the nodes around the circumfrence and linkages between the connected nodes. Adapted from the Mike Bostock's D3 Hierarchical Edge Bundling example using the htmlwidgets framework.

Usage

edgebundle(x, tension = 0.5, cutoff = 0.1, width = NULL, fontsize = 14, padding = 100, nodesize = c(5, 20), directed = FALSE)

Arguments

x

an appropriately structured JSON file (see vignette for details) or a square symmetric matrix (e.g. correlation matrix) or an igraph object.

tension

numeric between 0 and 1 giving the tension of the links

cutoff

numeric giving the threshold dependence for linkages to be plotted

width

the width of the plot when viewed externally

fontsize

font size of the node labels

padding

the padding (in px) between the inner radius of links and the edge of the plot. Increase this when the labels run outside the edges of the plot. Default: 100.

nodesize

two element vector of the min and max node size to scale the node circle size. If a size is not provided for each node, then the node size will be the max node size provided in this argument. Default: c(5,20).

directed

whether or not the graph is directed. Does not work yet. Need to think about how to implement this cleanly.

# ws_graph = watts.strogatz.game(1, 50, 4, 0.05)
# edgebundle(ws_graph,tension = 0.1,fontsize = 20)
