plot(bclust) what is the 2nd plot?
Hi everyone,
Currently i'm trying to understand the bagged clustering algorithm, bclust
{e1071}.
When I run the given example in the help file (as below)
data(iris)
bc1 <- bclust(iris[,1:4], 3, base.centers=5)
plot(bc1)
and plot the bclust object, 2 graphs are produced.
The first is a dendrogram, but what is the second plot? The axes are not
labelled and what do the two

about arguments in "bclust"
Hi All,
Just want to make sure, in function "bclust", do the following argument
only have one option?
argument "dist.method" has one option "Euclidian";
argument "hclust.method" has one option "average";
argument "base.method" has one option "kmeans".
Thank you!

Bagged clustering (package e1071)
Dear all,
I have a problem with the function "bagged clustering" of package

Post-hoc tests for repeated measures in balanced experimental design
Hi,
I am performing experiments in the field of visual perception where
we often apply balanced designs. Within a group of normal subjects,
we vary different stimulus conditions (like contrast, luminance,
temporal frequency of stimulation) and derive some psychophysical or
electrophysiological results from our subjects. Often, the main
question is to test the effect of these parameters

combining bclust and kkmeans
Hi,
I have a very large dataset of 3008 individuals and 800 numerical variables.
In fact it is a table of 3008 36-monthes multivariated time series that I
would like to classify with an unsupervised algorithm
I had a look at the function kkmeans of e1071 package, which seems to be a
kernel weighted version of the algorithm algorithm, and the bclust from the
same package which does bootstrapping

kmeans: "did not converge in 10 iterations"
Hi All,
I run function "kmeans" to cluster a matrix. But when the matrix size is
big enough, it keeps saying "did not converge in 10 iterations". Could
you explain what it means and if the result is wrong?
And the interesting thing is sometimes this warning happens when the
sample size is around 51200 x 6, sometimes it happens around 30000 x 6.

"partitioning cluster function"
Hi All,
For the function "bclust"(e1071), the argument "base.method" is
explained as "must be the name of a partitioning cluster function
returning a list with the same components as the return value of
'kmeans'.
In my understanding, there are three partitioning cluster functions in
R, which are "clara, pam, fanny". Then I check each of them to

Download limit
Hi all,
I am trying to use in RStudio the latest code given in

which seems to work fine but with the following warning for download
limits (one for each of the tickers).
I searched in options() something which could be related to this
setting, w/o success.
Any hint for me in order to raise or remove these limits? Where is this

encoding problem using xml package
Dear list
I tried to read an xml file using the xml package. Unfortunately, some encoding problems occure. E.g. german Umlaut will be red correctly. I assume that the occurs due to (internal?) conversion to utf-8. To illustrate the problem, I have wrote to xml files.

call R scripts from python
Hello,
I have just learnt some python, and would like to call R scripts from python, without using batch mode.
I learnt how to do it from perl, in fact reading in the mail archive I found the following good example:
***************************************
#!/usr/local/bin/perl
open (FILE, ">test.txt");
print FILE "a,b,c,d,e\n1,2,3,4,5";

reading excel into R
Dear all,
I am new R user and I am sure that this question has been asked quite often
and I have also googled it and read about it! I understood that in order to
read excel sheet into R you need to open it and saved it as csv or text, is
this true? or you can use read.delim2 and read.csv2 to do this without the
following error
