cannot use fanny in package cluster
Dear All,
My R version: 2.0.1 ; OS using: Linux. I install the package cluster by
using install.packages("cluster"). After install it, it runs fine for
function clara, but it does not work for function fanny. I did the following
things:
library(cluster)
set.seed(21)
x <- rbind(cbind(rnorm(10, 0, 0.5), rnorm(10, 0, 0.5)),cbind(rnorm(15, 5,
0.5), rnorm(15, 5, 0.5)),cbind(rnorm(

"FANNY" function in R package "cluster"
Dear All,
I am attempting to use the FANNY fuzzy clustering function in R
(Kaufman & Rousseeuw, 1990), found in the "cluster" package. I have
run into a variety of difficulties; the two most crucial difficulties
are enumerated below.
1. Where is the 'm' parameter in FANNY?

Predict Fanny Membership
Hello List,
My question is an elementary one. I have run a fuzzy kmeans cluster using
FANNY to group freshwater fish assemblages. I then went in the field to
validate that classification and have retrieved new assemblage data for a
new suite of streams. Therefore I would like to use Predict to determine how
well the original clustering fits the new data. However I have not figured
out a

cluster results using fanny
Hi,
I am using fanny and I have estrange results. I am wondering if
someone out there can help me understand why this happens.
First of all in most of my tries, it gives me a result in which each
object has equal membership in all clusters. I have read that that
means "the clustering is entirely fuzzy". Looking at the graphics it
is really difficult to understand how objects with so

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?

Ideal number of clusters using the Fanny algorithm
Hello,
Could someone please let me know the procedure for determining the 'best'
solution with regards to the number of clusters using the Fanny algorithm
for computing fuzzy clusters? The function requires a specification of the
number of clusters a priori, but I am interested in determining what number
of clusters would result in the ideal fit with the data. Any

Cluster package broken in 1.4.0?
Greetings,
I am reasonably experienced with R but I recently tried to
do some clustering using the "cluster" package, in order
to see if it would help.
I only tried this once with the 1.3.1 version and it worked
(I don't quite remember which method I used).
Now, I tried with the 1.4.0 version and no clustering function
seems to work with matrices that contain NAs, even

PAM clustering: using my own dissimilarity matrix
Hello,
I would like to use my own dissimilarity matrix in a PAM clustering with
method "pam" (cluster package) instead of a dissimilarity matrix created
by daisy.
I read data from a file containing the dissimilarity values using
"read.csv". This creates a matrix (alternatively: an array or vector)
which is not accepted by "pam": A call

fuzzy classification and dissimilarity matrix
Hello,
I want to make a fuzzy classification from a dissimilarity matrix
(calculated with daisy from package 'cluster'). I have tried to use
fanny (package cluster) but I have 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)

"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

predicting fuzzy cluster membership
Dear all,
I'm trying to obtain a fuzzy clustering with fanny from the cluster package,
using a given set of data. That worked just fine.
I have another separate sample of data from the same problem. For each case in
this new sample I would like to know their membership coefficients with
respect to the clustering obtained with the first dataset. In effect I want
to have a kind of prediction

Clustering partition and memory
Dear R-help list members
i would like to use R to produce clustering or partitioning of a dataset.
I am trying to use the functions:
- hierclust() of the package multiv
-pam(), agnes() and fanny() of the package cluster
But I cannot get any result because of lack of memory. Would you know any
clustering function not to greedy in memory?
I have tried to expand my memory limit with memory.limit()

legend - bug with argument angle (PR#1404)
When legend() is used with the angle argument as follows, not only the
boxes beside the legend text, but also the whole legend box is filled
with shading lines.
I think this is not intended:
plot(1:10)
legend(8, 4, c("A", "B"), angle=c(10, 80), fill=NULL, density=20)
I'd suggest as a fix (legend.R of R-1.5.0):
