Modify the edge size of a 'sigmaNet' object.

Modify the edge size of a 'sigmaNet' object by providing one of the following: (1) a single size to use for all edges; or (2) an attribute in the initial igraph to be used to size the edges.

addEdgeSize(sigmaObj, sizeAttr = NULL, minSize = 1, maxSize = 5,
  oneSize = NULL)

Arguments

sigmaObj	A 'sigmaNet' object - created using the 'sigmaFromIgraph' function
sizeAttr	The attribute to use to create edge size (width)
minSize	The minimum size of the edges (for scaling)
maxSize	The maximum size of the edges (for scaling)
oneSize	A single size to use for all edges

Value

A 'sigmaNet' object with modified node labels. This object can be called directly to create a visualization, or modified by additional functions.

Details

If the 2nd method is used, the minSize and maxSize attribute will control lower and upper bounds of the scaling function.

Examples

library(igraph)
library(sigmaNet)
library(magrittr)

data(lesMis)

l <- layout_nicely(lesMis)

#specify a single edge size
sig <- sigmaFromIgraph(graph = lesMis, layout = l) %>%
  addEdgeSize(oneSize = 5)
sig

#specify an attribute and min/max
sig <- sigmaFromIgraph(graph = lesMis, layout = l) %>%
  addEdgeSize(sizeAttr = 'value', minSize = .1, maxSize = 2)
sig
