dissimilarity matrices
Dear All,
I have a dissimilarity matrix which I happily convert to a distance object
by running:
X <- as.dist(Y)
and I can happily now run either hclust(X) or agnes(X).
So that the various bits of output are labelled correctly I would dearly
like to be able to give names to the columns and rows of X, as would happen
if I ran:
mydata<-read.table("clipboard",header=T)

HFSC parameter
My problem with HFSC tc command is ...
tc command''s HFSC have a lot parameter with 4 curve type
SC curve -> umax dmax rate
LS curve -> umax dmax rate
RT curve -> umax dmax rate
UL curve -> umax dmax rate
so i''dont know which parameter are appropriate for my test case
such real time class which curve are appropriate and good working result.

Possible bug: TC with HFSC fails to load if umax is not provided
I stumbled upon a problem while upgrading Ubuntu 13.04, Shorewall version
from 4.4.26.1 to 4.5.16.1.
Everything was working fine before, after upgrading the script wouldn''t
start.
First some config files.

cluster analyses
I'm clustering rather large data sets and would like to cut the dendrograms
to get a better view of specific components. I calculate the dissimilarity
matrix using daisy() because I have a mixture of variable types: factors,
ordered factors and numerical variables. If I want one dendrogram, I use
agnes() for the agglomerative nesting and pltree() to draw the dendrogram.
That way, I get the

Dendrogram for many cases
Dear All,
I have a cluster object based on a
dissimilarity matrix from about 1,100
cases and wish to know whether anyone
can think of any tips to display some
form of graphical output which would
give some sense of the similarity
between the cases.
A standard form of dendrogram would be
fine, but with so many cases the
dendrogram on the standard devices
(R-2.20 on NT4) is very compact

questions on plotting dedrograms
Hi,
i've two questions concerning the plot of a dendrogram. first, i use
hclust for clustering and if i plot the dendrogram, then the maximal
height is the maximal dissimilarity found in my data. but i want to have
a arbitary maximal height. for example if the maximal dissimilarity in
my data is 50 and i want a height of 100, the plot should be compressed
by 1/2 and the line to the root

Specify ID variable in daisy{cluster}
Hi All - I am using the daisy function from the cluster library to create a
dissimilarity matrix. I'm going to use that matrix to run a cluster
analysis. My participants are identified with the variable, hhid. However,
when I try to keep hhid in the dataset that I use to create the
dissimilarity matrix, daisy uses it to create the matrix rather than
ignoring it as an ID variable. I need to

AW)Dmax and Windows XP
Hi
do anyone have experience of the Abit AW9D-MAX. I try to run a native
windowsXP under Yast2 control on a xen from suse10.2. I get an error
claiming that APIC is not enabled. However if I look in boot.msg it says
enabled for 0x00 och 0x01 but not 0x02 and 0x03
LAPIC (acpi_id[0x00] lapic_id[0x00] enabeled) and so on
any suggestions?

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.

Best way to organize this data for plotting
Hello
I have a number of data files which are outputs for each step of a
simulation. The data is organized like this:

3 8 0.098056
5 6 0.425926
6 6 0.517860
2 4 0.527778
I would like to make a 3-d plot where one axis corresponds to (dmin,
dmax) pair, one axis is the simulation

Jaccard dissimilarity matrix for PCA
Hi
I have a large dataset, containing a wide range of binary variables.
I would like first of all to compute a jaccard matrix, then do a PCA on this
matrix, so that I finally can do a hierarchical clustering on the principal
components.
My problem is, that I don't know how to compute the jaccard dissimilarity
matrix in R? Which package to use, and so on...
Can anybody help me?

questions about HFSC, VoIP and (dynamic) ingress shaping
Hello,
I just found the great howto and started shaping my internet connection. The
howto''s last update is a liitle in the past now so I have some questions
about how things are done the best way nowadays ;-)
To ensure a stable and low latency voip communication I added an HFSC qdisc to
device ppp0 (1 Mbit SDSL). There are two classes (by now): One for SIP and
RTP and one for the
