In ReorderCluster: Reordering the Dendrogram According to the Class Labels

Makes the plot of the dendrogram, visualizing the class label information with different colors of dendrogram edges.

Description

Makes the plot of the dendrogram, visualizing the class label information with different colors of dendrogram edges.

Usage

colorDendClass(dend, class)

Arguments

dend	the clustering dendrogram of the analyzed dataset.
class	a vector of length n, which stores the class labels of the dataset objects.

Details

Makes the plot of the dendrogram, visualizing the class label information with different colors of dendrogram edges.

Examples

data(leukemia)
rownames(leukemia)=leukemia[,1]
leukemia=leukemia[,-1]
matr=leukemia[,-101]
class=leukemia[,101]

matr=as.matrix(matr)
dist=dist(matr)
hc <- hclust(dist)
dend=as.dendrogram(hc)

label=unique(class)

Rowcolor=rainbow(length(label))
rc=matrix(0,length(class),1)

for (j in 1:length(label))
{
		index=which(class==label[j])
		rc[index]=Rowcolor[j]
}

colorDendClass(dend,rc[hc$order])
