Cannot convert from phylo to hclust , error!!???
Hello,
The following code does'nt work for me. The last command reports an error. I
have created a consensus tree using the consensus comand from phylo but
cannot manipulate the phylo object afterwards to create a dendogram , by
transforming the phylo object into a hclust object and then into a dendogram
??
Thanks for any help

Is there a way to print branch distances for hclust function?
The R function hclust is used to do cluster analysis, but based on R
help I see no way to print the actual fusion distances (that is, the
vertical distances for each connected branch pairs seen in the cluster
dendrogram).
Any ideas? I'd like to use them test for significant differences from
the mean fusion distance (i.e. The Best Cut Test).
To perform a cluster analysis I'm using:

different hights & centering in one device region
Hello,
I have a question. I creat a PDF file with four rows and
two cols.
Is it possible to:
-create a plot regions with different hights (example: rows 1 & 2-4)
-ro center an image in the whole width (example: rows 4)
Thank's a lot.

How do I get internal nodes of dendograms produced by R?
I am using R for hierarchical clustering of a number of documents.
I have a distance matrix on which I have applied hclust method. When I plot
the result of hclust method, I can see the dendogram plotted. What I need
now is the dendogram stored as a tree in a data structure. My goal is to
automatically label all internal nodes. For that, I need to know, which
leaf nodes make a first level

community finding in a graph and heatplot
Hi everyone,
I am using the fastgreedy.community function to get the $merges matrix and the $modularity vector. This serves my purpose of testing modularity of my graph. But I am "greedy" to plot the heat map and dendrrogram based on the $merges dendogram matrix. I know that heatplot does the graphics part but I am not sure if the dendogram generated by the heatplot will match the one

2 questions about cluster analysis
Hello everyone!
I have two questions regarding cluster analysis with the package 'cluster'
:
1. I have a dissimilarity matrix in csv format, and I would like to use
it to generate a dendogram using 'hclust'. How do I make that matrix
compatible with the function? I think it has to be similar to the objects
generated by the 'dist' function. Any ideas?

Coloured label, terminal branch and bars in dendograms

I have performed a hierarchical clustering on some data that I have and

is my inelegant way of just getting the colored labels.

cpu frequency scaling in domUs
Hi,
I''ve recently installed xen-3.2.1 on my AMD Sempron(tm) machine.
It runs gentoo 2.6.21 as dom0 and cpu frequency scaling works in dom0.
But inside a domU, cpu frequency scaling is not working.
By checking the boot log in domU I found that domU is unable to load the
powernow driver:
"powernow-k8: BIOS error - no PSB or ACPI _PSS objects"
I wonder if it is possible to have

Support for CPU frequency scaling in Xen
Hi,
Does Xen provide support for CPU frequency scaling?
If there exists such support, from which version they support it?
Otherwise what problems do exist in support frequency scaling in Xen?
Thanks,

"reversed" dendogram
Dear All,
I am trying to find a way to plot a dendogram in reverse, that is,
if the terminal leaves are labelled 1-10 bottom to top (or left to
right), I would like to be able to plot it in a way such that if
would display 10-1 bottom to top or left to right. Any idea how to
achieve this?
Thanks in advance,

heatmap.2 dendogram algorithm
Hello
does anyone know what algorithm is used to produce the hierarchical
clustering in the gplots package using the function heatmap.2? I think it
may be the complete linkage clustering algorithm, but I can't find a source
that seems reliable.
Thank you and sorry if I posted this in the wrong place. If I have, please
let me know and I will move it to the appropriate list.
