Plot graph with the option of using different colors for connected components

Description

This function plots the graph of the data frame and optionally uses different colors for nodes belonging to different connected components.

Usage

networkPlot(
  df,
  title = NULL,
  numCol = NULL,
  numColType = c("weights", "ranks"),
  nodeSize = 10,
  nodeTextSize = 2.3,
  palette = "grDevices::Spectral",
  nodeColor = NULL,
  edgeWidth = 1,
  edgeColor = "black",
  edgeScales = c(0.2, 0.6),
  ...
)

Arguments

df	Data frame.
title	Plot title.
numCol	Name of the numeric column used to vary edge widths. If no such column is provided, set to NULL.
numColType	The type of the numeric column used to vary edge widths. Choose between 'weights' and 'ranks' Ignored if numCol is NULL.
nodeSize	Size of graph nodes.
nodeTextSize	Size of text on graph nodes.
palette	grDevices palette used for coloring nodes. Ignored if nodeColor is not NULL.
nodeColor	Color used for nodes. Default is NULL (palette will instead be used).
edgeWidth	Width to be used for all edges before scaling if numCol is NULL; otherwise ignored.
edgeColor	Color used for edges.
edgeScales	Edge width scales. Must be a numeric vector of size 2 (minimum and maximum).
...	Additional arguments passed to centerTitle.

Value

An object of class ggraph.

Examples

df <- data.frame(gene1 = paste0('G', c(1, 2, 5, 6, 7, 17)),
gene2 = paste0('G', c(2, 5, 8, 11, 11, 11)),
rank = c(1, 1, 3, 3, 3, 3))
networkPlot(df, numCol='rank', numColType='ranks')
