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 t...

How to build a "Amalgamation Schedule"? help!
Dear all,
I need to process large amounts of data (two or three variables for 6,000
cases) cluster analysis. In the end I need to fill the source data to the
obtained clusters. I need to trace the sequence of data fusion. In this
case, I can fill in a cluster (with any level of linkage distance) by data.
This procedure is implemented in the package Statistica, but this package
can not work with

plotting multiple data sources
hi,
Excuse me asking three questions in a row for a day, but I had
collected those questions
as I'm still experimenting with R.
This one is how do you compose plots with alot of data in one graph.
First what I currently do is after i generated all the data I need to
plot.. let say 5-6 arrays
I do a plot() and then I created a function to scale the other data to
approx fit the initial range
so

Clustering question \ dist(datmat)
Hello everybody. I am trying to cluster circular data (data points which are angles), thus i can not use the "dist" function in "mclust" to generate my distance matrix, I am using the function " Dij = 0.5*( 1 - cos(theta_i - theta_j)). The thing is "hclust" will not accept this distance matrix, i tried to put it in a data frame, but again i get an error message
