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 b...

Clusteranalysis
Hello,
in marketing-science field i do some
clusteranalysis and get the experience that
the scale cause the results dramatic!
What recommendation can somebody give me, when i use
nominal-variables(recode to 0/1 variables) with
6 point ordinal-variables.
Is it better toDo a z-transformation with the ordinal variables
, or should i recode this values in 0/1...

Clusteranalysis Chi-square test and SingleLinkage
..."hclust"
hclust(d, method = "complete", members=NULL)
But the R reference says d must be "a dissimilarity structure as produced by
dist."
But the dist function does not have a method chisquared-test or something
similar.
So does anybody have an idea how I can do a clusteranalysis with a
chi-squared test and then use a fusion algorithm to join the clusters?
Thanks

clusteranalysis dendrogram
Dear all,
i have a little trouble with cutting an understanding the handling of
dendrogram and hclust.
plotting clusters does work and it delivers a dendrogram. the problem
is that the dendrogram shows lots of pretty small clusters and only
some larger ones.
i know that this has to do with my data. But is there possibility to
tell the plot function just to plot the clusters with more than

tcltk
HI,
(1) ...thanks for the last comments to tcltk & Win2000.
(2) - i'm newbie in tcl/tk but would like learn fast and develop
(learning by doing) a tcl/tk clusterAnalysis application which combine
some clusterMethods from different Rpackages.
i use the tkttest.R example as "reference" and become not finished for
my "first" step????
(3) how is it possible that the code from the tkttest.R example would
be execute and not only print to the screen;...

MDS with ranking data (and transformation)
...the data in some other format, e.g. with colloumns:
"philospher_1", "philospher_2", "philospher_3" etc. and then have the cell
hold the particular ranking (score) for that philospher (i.e. a number
between 1:10)
I guess such a transformation would also allow me to do clusteranalysis? -
But how to do it???
Anyways: what I have done so far is to compute a 10*10 matrix in a
spreadsheet application. I do this by
countif(range_choice1=philospher1)*10 for each philospher.
In ?range_choice2? I multiply by 9, and in ?range_choice3? I multiply with 8
etc.
The corresponding matrix I i...
