Formatted Data File Question for Clustering -Quickie Project
I am trying to learn how to format Ascii data files for scan or read
into R.
Precisely for a quickie project, I found some code (at end of this
email) to do exactly what I need:
To cluster and graph a dendrogram from package (stats).
I am stuck on how to format a text file to run the script.
I looked at the dataset USArrests (which would be replaced by my data
and labels) using UltraEdit. That

Colored Dendrogram
Hi all,
I am a real novice to R. :)
I am struggling with a problem for generating colored dendrogram. I have
searched the R list and complied/collected a R code which can generated a
colored dendrogram based on the rainbow color and 4x4 similarity matrix (say
matrix:m).
In this dendrogram, each leaf is colored differently. But, I do not want the
leaf colored on a random basis. I want to assign

horizontal labels for a dendrogram
Dear R-help list,
I'd like to create visualize the clustering of a dataset with a
dendrogram. I'm using the following script:
data = read.table("data.csv", header=T, sep=";")
require(cluster)
res = as.dendrogram(agnes(data))
chlab <- function(n) {
if(is.leaf(n)) {
att <- attributes(n)
labx <- data$category1[att$label]

Lattice: problem with setting space between plot and legend
Dear R Users,
I am writing code to present my output data (I'm using Lattice Package).
However, it's essential for me to control space between barchart and legend.
I've read the package's specification, but unfortunately I haven't spot the
information how to do this. Here's the code I've written:

Coloring leaves, twigs and labels in plot.dendrogram()
Core developers,
I couldn't find any simple way to send a vector of colors to apply to each
terminal in plot.dendrogram() or plot.hclust()---I asked R-help about it a
few weeks ago and didn't get any response---so I hacked that functionality
into the plot.dendrgram code (see below for hacked function plus
examples)....
Is there any chance this functionality could be added to the

Generate Dendrogram
Hi
I have a distance matrix which is computed by user defined method. I
would like to plot the dendrogram. I would like to use different color
and want the leaves laying down bottom.
The script like this. I am not familiar with R. I followed the example
shown in

dendrogram stops!
Dear I am using the 'as.dendrogram' function from the 'stats' library to convert from an hclust object to a dendrogram with a dataset of size
~30000 (an example code is below). I need the dendrogram structure to
use the "dendrapply" and "attributes" functions and to access the child
nodes, I do not need any of the plot properties.
The problem is that it

Colouring hclust() trees
I have a data set with 6 variables and 251 cases.
The people who supplied me with this data set believe that it falls
naturally into three groups, and have given me a rule for determining
group number from these 6 variables.
If I do
scaled.stuff <- scale(stuff, TRUE, c(...the design ranges...))
stuff.dist <- dist(scaled.stuff)
stuff.hc <- hclust(stuff.dist)

Defining plot colors based on a variable
Hi, I have been trying unsuccessfully to plot data using different colors
based on a variable within a subset of an imported file. The file I am
reading is about 20000 lines long and has a column (in the example called
FILE) that contains approximately 100 unique entries. I would like to plot a
subset of the data from the file and key the color from the FILE column,
This is what my file looks like

dendrogram / clusteranalysis plotting
Dear all,
i performed a clusteranalysis - which worked so far...
i plotted the dendrogram and sooo many branches, a rough sketch would
be enough ;)
i tried max.levels therefore which worked, but not for the plot...
i used the following
plot(hcd,nodePar =nP, str(hcd,max.level=1))
the output on the terminal was:
--[dendrogram w/ 2 branches and 196 members at h = 2.70]

Hierarchical clustering using own distance matrices
Hey Everyone!
I wanted to carry out Hierarchical clustering using distance matrices i have
calculated ( instead of euclidean distance etc.)
I understand as.dist is the function for this, but the distances in the
dendrogram i got by using the following script(1) were not the distances
defined in my distance matrices.

Static/Breaking up after I upgraded Asterisk aswell as a crash - Can't trace bug
I am also running a pretty recent version albeit not today's CVS, but
CVS-HEAD-11/20/04-11:29:52.
D you have problems b/w the Ciscos or only when going out to the PSTN??
I have 35 7960s with a PRI and no problems that you speak of. I do get
an occational dropped call but that may be the DHC server lease running
out on the phones.
Can you tell us a little more about your setup???

Static/Breaking up after I upgradedAsteriskaswell as a crash - Can't trace bug
If your remotes are not reporting any trouble. This may be farfetched but power may be to blame. I have had the ciscos 'freak out' with unstable power. It looks like the load on the power cubes cannot keep the caps loaded to deal with fluctuations. Or you may have a ground loop somewhere.
Are the phones plugged into UPSs?
I had flaky 7960 work fine after pluged into a Cisco POE switch.

a. crossing branches with hclust, b. plot.dendrogram
Hello,
a. when I use hclust with the methods media, centroid, and mcquitty,
and plot the results, the dendrograms have lines that are crossing each
other. Is this ok?
b. My next question refers to plot.dendrogram: How can I use parameters
as "hang" or "cex" here? E.g. for
st <- as.dendrogram(subtreeshc[[x]])
I would like to have something like this, where cex and hang

coloring leaves in clustering
Hello everyone,
I wanted to know if it was possible to change the color of certain leaves in
a hclust object in order to make my graph more readable. I know I can color
certain groups but I would like to enter a vector telling the plot function
which leaves to color in which color.
Thanks in advance,
Eleni
