error en un cmeans
Tuve que dejar, de momento, lo del "loop con matriz que cambia de
nombre" por algo más urgente, y me salió otro problema.
Hago un cmeans con el paquete e1071;
cl<-cmeans(Data,i,20,verbose=F,method="cmeans",m=2)
y me da este error: Error in apply(u, 1, which.max) : dim(X) must
have a positive length.
Estoy harto de usar esa línea de código, con dfs iguales a la de
ahora, por lo que no entiendo por qué falla....

Effect of data set size on calculation
Dear listers,
I have a piece of code which performs an ANOVA type of analysis on 2D GC
data. The code is shown below:

# nreps <- number of samples
maxc <- 2
nreps <- 4
sscl <- NULL
cmean <- NULL
#
# Initial stat. variable

Where can I find cmeans {e1071} package?
Hello,
I need a Fuzzy C Means algorithm.
I found some documentation about cmeans {e1071} at
http://rss.acs.unt.edu/Rdoc/library/e1071/html/cmeans.html
Does someone knows where I can find it?
Thank you

How to create a cmeans plot
Hi all R-helpers!!!
I?m a Newbie to R and I have only one small question:
Is there any possibility to plot a cmeans (package
e1071) cluster result? Or any other possibility of
visualisation like with the algorithm fanny? I
couldn?t find any information how to create a plot
with cmeans on the R help page.
Thanks in advance!

MPI implementations of fanny or cmeans
I've done a little digging, but I haven't been able to find an MPI or
snow (or any other distributed processing) implementation of fanny
(from cluster) or cmeans.
Is anyone aware of some implementations or addons which I've missed?
[I know of doi://10.1007/978-3-540-71351-7; but that's not for R]

fuzzy classification and dissimilarity matrix
...ve the same problems than described in a
previous message
(http://tolstoy.newcastle.edu.au/R/help/05/05/4546.html) i.e. it always
gives me two clusters in the results (even if k is different from 2)
with the same memberships for all cluster. One solution suggested to the
previous message was to use cmeans from package e1071. The problem is
that it seems that cmeans doesn't work with dissimilarity matrix and I
have to use daisy because I have mixed data.
What can I do ?

- Formula Interface
- k-fold cross-validation
In addition, an introductory article is provided in directory
`docs/' (svmdoc.pdf).

o updated API design for the fuzzy clustering functions
(cmeans, cshell, scaclust). Documentation updates and function
name changes (cmeanscl -> cmeans, validity.measures -> fclustIndex)

AW: non-hierarchical non-exclusive clustering of large data sets
I think the "cmeans" method in library(e1071) works better for large data sets as "fanny".
(note,not for this data: fanny has also problems with standardized large data sets - here produce fanny the same memberships for all observations; cmeans works "correctly")
