visIgraphLayout: Use a igraph layout for compute coordinates & fast rendering

Description

Use a igraph layout for compute coordinates and fast rendering. This function affect x and y coordinates to nodes data.frame using a igraph layout, and then render network faster with no stabilization. We set some options as : visNodes(physics = FALSE) & visEdges(smooth = FALSE) & visPhysics(stabilization= FALSE), but you can overwrite them using arguments or by add another call after visIgraphLayout

Usage

visIgraphLayout(graph, layout = "layout_nicely", physics = FALSE, smooth = FALSE, type = "square", randomSeed = NULL, layoutMatrix = NULL, ...)

Arguments

graph

: a visNetwork object

layout

: Character Name of igraph layout function to use. Default to "layout_nicely"

physics

: Boolean. Default to FALSE. Enabled physics on nodes ?

smooth

: Boolean. Default to FALSE. Use smooth edges ?

type

: Character Type of scale from igrah to vis.js. "square" (defaut) render in a square limit by height. "full" use width and height to scale in a rectangle.

randomSeed

: Number. The nodes are randomly positioned initially. This means that the settled result is different every time. If you provide a random seed manually, the layout will be the same every time.

layoutMatrix

: in case of layout = 'layout.norm'. the 'layout' argument (A matrix with two or three columns, the layout to normalize)

...

: Adding arguments to layout function
