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