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. |
