SPADE.layout.arch: Generate coordinates for plotting graphs

In nolanlab/spade: SPADE -- An analysis and visualization tool for Flow Cytometry

Description

Performing "arch" layouts of graph vertices

Usage

SPADE.layout.arch(mst_graph)

Arguments

mst_graph

The graph to layout. Must be acyclic and undirected.

Details

These functions calculate the coordinates of the vertices for a graph.

layout.arch lays out the longest chain of the graph, the "backbone", on an arch, and the "side chains" as trees normal to that backbone.

Value

All these functions return a numeric matrix with at least two columns, x and y positions, and the same number of lines as the number of vertices.

Examples

	# Not run
	## Load two-parameters sample data included in package
	#data_file_path = paste(installed.packages()["spade","LibPath"],"spade","extdata","SimulatedRawData.fcs",sep=.Platform$file.sep)

	## Run basic SPADE analyses, clustering on two parameters. 
	#output_dir <- tempdir()
	#SPADE.driver(data_file_path, out_dir=output_dir, cluster_cols=c("marker1","marker2"))

	## Generate PDFs of annotated graphs (into output_dir/pdf) using arch layout
	#mst_graph <- igraph:::read.graph(paste(output_dir,"mst.gml",sep=.Platform$file.sep),format="gml")
	#SPADE.plot.trees(mst_graph, output_dir, out_dir=paste(output_dir,"pdf",sep=.Platform$file.sep), layout=SPADE.layout.arch(mst_graph))
