Analyzing dendograms??
I have used heatmap to visualize my microarray data. I have a matrix of
M-values. I do the following.
#The distance between the columns.
sampdist <- dist(t(matrix[,]), method="euclidean")
sclus <- hclust(sampdist, method="average")
#The distance between the rows.
genedist <- dist(matrix[,], method="euclidean")
gclus <- hclust(genedist, method="average")
heatmap(matrix[,],Rowv=as.dendrogram(gclus),Colv=as.dendrogram(sclus), col=rbg)
So far so good. B...

The problem happens when trying to plot a large dendrogram.
