sgraph (version 1.1.0)

add_node_size: Modify the node size of a sgraph object.

Description

Modify the node size of an existing sgraph object by providing either: (1) A single size to use for all nodes; (2) a vector of node sizes; or (3) a metric to use to scale the nodes.

Usage

add_node_size(
  sigma_obj,
  min_size = 1,
  max_size = 3,
  one_size = NULL,
  size_vector = NULL
)

Value

A sgraph object with modified node sizes

Arguments

sigma_obj

sgraph object, returned by sigma_from_igraph function

min_size

Minimum node size on the graph (for scaling)

max_size

Maximum node size on the graph (for scaling)

one_size

A single size to use for all nodes

size_vector

An optional vector with the sizes for each node

Examples

library(igraph)
library(sgraph)

data(lesMis)

layout <- layout_nicely(lesMis)

# one size for all nodes
sig <- sigma_from_igraph(igraph = lesMis, layout = layout) %>%
  add_node_size(one_size = 3)
sig

# using a vector
custom_size <- log10(degree(lesMis))
sig <- sigma_from_igraph(igraph = lesMis, layout = layout) %>%
 add_node_size(size_vector = custom_size)
sig
