I recommend that you start with the documentation and examples for the
'heatmap' function. This creates heatmaps of your underlying data,
augmented by optional dendrogram representations of clusterings of
your rows (could be genes) and columns (could be arrays). In its
default mode, it performs the clustering for you and it will do
agglomerative hierarchical, I believe. Start there and get
Then, you can do something more advanced -- namely, request a
non-default clustering method. You maybe able to do this using the
'hclustfun' argument of 'heatmap' (i.e. specify 'diana' here) or you
could perform your clustering in advance, using 'diana' if you like,
and pass those results as dendrograms to 'heatmap'.
Can't help you with Treeview.
Good luck, Jenny
