Neither ContigID nor sampleID are defined in your example. The default
is to plot by the row names. You can get the manual page for the
dendrogram plot using the command ?plot.hclust. The second argument
lets you specify the labels.

Hi,
I do have RNAseq FPKM count and interested in dendrogram for samples
cluster.
I used below code but it generate dendogram based on ContigID instead of
sampleID.
