plotSPW {DRviaSPCN}

Plot subpathway network graph

Description

The function plotSPW can visualize subpathway network graph.

Usage

plotSPW(
  subpathwayID,
  layout = NULL,
  margin = 0,
  vertex.label.cex = 0.8,
  vertex.label.font = 0.8,
  vertex.label.dist = 1,
  vertex.size = 12,
  edge.arrow.width = 3,
  edge.label.cex = 0.6,
  vertex.label.color = "black",
  vertex.color = "#F08080",
  vertex.frame.color = "dimgray",
  edge.color = "grey70",
  edge.label.color = "dimgray",
  sub = NULL,
  main = NULL
)

Arguments

subpathwayID

Subpathway id .A character vector.

layout

A matrix of x-y coordinates with two dims. Determine the placement of the nodes for drawing a graph.

margin

A numeric. The value is usually between -0.5 and 0.5, which is able to zoom in or out a subpathway graph. The default is 0.

vertex.label.cex

A numeric vector of node label size.

vertex.label.font

A numeric vector of label font.

vertex.label.dist

A numeric vector of label dist.

vertex.size

A numeric vector of Node size. See plot.igraph.

edge.arrow.width

Edge arrow width. The default is 3.

edge.label.cex

Edge label size.

vertex.label.color

A vector of node label colors. The default is black.

vertex.color

A vector of node colors. The default is the KEGG node color.

vertex.frame.color

A vector of node frame color. The default is dimgray.

edge.color

A vector of edge color. The default is dimgray

edge.label.color

A vector of edge label color. The default is dimgray.

sub

A character string of subtitle.

main

A character string of main title.

Value

a subpathway map

Examples

# load depend package
library(igraph)
# plot network graph of the subpathway "00020_4"
