plotGraphSpace-methods: Wrapper function to plot GraphSpace objects in ggplot2

In RGraphSpace: A Lightweight Interface Between 'igraph' and 'ggplot2' Graphics

Wrapper function to plot GraphSpace objects in ggplot2

Description

plotGraphSpace() is a High-level plotting interface that translates igraph and GraphSpace data objects into ggplot2 layers.

Usage

## S4 method for signature 'GraphSpace'
plotGraphSpace(
  gs,
  theme = "th0",
  xlab = "Graph coordinates 1",
  ylab = "Graph coordinates 2",
  font.size = 1,
  bg.color = "grey95",
  add.labels = FALSE,
  node.labels = NULL,
  label.size = 3,
  label.color = "grey20",
  add.image = TRUE,
  raster = FALSE,
  dpi = 300,
  dev = "cairo_png"
)

## S4 method for signature 'igraph'
plotGraphSpace(gs, ...)

## S4 method for signature 'tbl_graph'
plotGraphSpace(gs, ...)

## S4 method for signature 'gs_graph'
plotGraphSpace(gs, ...)

Arguments

gs	Either an igraph or GraphSpace class object. If gs is an igraph, then it must include x, y, and name vertex attributes (see GraphSpace).
theme	Name of a custom RGraphSpace theme. These themes (from 'th0' to 'th3') consist of preconfigured ggplot settings, which can subsequently refine using ggplot2.
xlab	The title for the 'x' axis of a 2D-image space.
ylab	The title for the 'y' axis of a 2D-image space.
font.size	A single numeric value passed to ggplot themes.
bg.color	A single color for background.
add.labels	A logical value indicating whether to plot vertex labels.
node.labels	A vector of vertex names to be highlighted in the graph space. This argument overrides 'add.labels'.
label.size	A size argument passed to geom_text.
label.color	A color passed to geom_text.
add.image	A logical value indicating whether to add a background image, when one is available (see GraphSpace).
raster	A logical value indicating whether to rasterize the main plot. See rasterise for further specifications.
dpi	Raster resolution, in dots per inch.
dev	Device used in the rasterise call.
...	Additional arguments passed to the plotGraphSpace function.

Value

A ggplot-class object.

Examples

library(RGraphSpace)
library(igraph)

# Load a demo igraph
data('gtoy1', package = 'RGraphSpace')

# Generate a ggplot for gtoy1
plotGraphSpace(gtoy1)

# Create a star graph
gtoy_star <- make_full_graph(15)

# Example of setting node and edge attributes
V(gtoy_star)$nodeSize <- 5
E(gtoy_star)$edgeLineColor <- "red"
E(gtoy_star)$arrowType <- "<->"

# Create a GraphSpace object
gs_star <- GraphSpace(gtoy_star)

# Normalize graph coordinates
gs_star <- normalizeGraphSpace(gs_star)

# Generate a ggplot for gs_star
plotGraphSpace(gs_star)
