Are there any package that is using v-fold cross-validation algorithm
to test the number the clusters?
Thanks,

Hi,
I'm wondering whether there is GUI under linux. I checked the website,
it has Emacs(ESS), IDE/Scrip Editors etc. I am looking for one which is
similar to the GUI under windows.
Thanks,
Ming

Thanks for all the good points. I raised the question not because I doubt the R
system, but I think it is a common point for all the open code software.
Personally I really appreciate the open source software, and nowadays,
there are more and more open source, especially in the academic area.
The cluster analysis should be able to handle that. I think if you
know how many clusters you have, kmeans is ok, or the EM algorithm
can also do that.

Hi,
I am looking for a package to do the clustering analysis using the
expectation maximization algorithm.
Thanks in advance.

Dear all,
I am beginner using R. I have a question about it. When you use it,
since it is written by so many authors, how do you know that the
results are trustable?(I don't want to affend anyone, also I trust
people). But I think this should be a question.
Thanks,

Hi,
I am new here.
I used y-kmeans(x, 2)(x is a vector) to do the cluster analysis. I get
y has $cluster, $center etc. I need to pull out the data belong to
cluster 1 and cluster 2. How can I do that?
Thanks,
Ming
