In junyzhou10/test: Citrus: Identification of stratifying subpopulations in Flow Cytometry Data.

Description

Create a graph object from clustering hierarchy that may be used by other plotting functions.

Usage

citrus.createHierarchyGraph(citrus.clustering, selectedClusters)

Arguments

citrus.foldFeatureSet	A citrus.foldFeatureSet object. Clusters for which features are calculated are included in the graph.
citrus.foldClustering	A citrus.foldClustering object. Used to determine relationships between clusters.

Value

A graph object and other properties for plotting.

graph	An igraph graph object.
layout	An igraph layout for the graph.

Examples

# Where the data lives
dataDirectory = file.path(system.file(package = "citrus"),"extdata","example1")

# Create list of files to be analyzed
fileList = data.frame("unstim"=list.files(dataDirectory,pattern=".fcs"))

# Read the data
citrus.combinedFCSSet = citrus.readFCSSet(dataDirectory,fileList)

# List of columns to be used for clustering
clusteringColumns = c("Red","Blue")

# Cluster data
citrus.clustering = citrus.cluster(citrus.combinedFCSSet,clusteringColumns)

# Large enough clusters
largeEnoughClusters = citrus.selectClusters(citrus.clustering)

# Create graph for plotting
hierarchyGraphStuff = citrus.createHierarchyGraph(citrus.clustering,selectedClusters=largeEnoughClusters)
