cclust causes R to crash when using manhattan kmeans
Dear R users,
When I run the following code, R crashes:
require(cclust)
x <- matrix(c(0,0,0,1.5,1,-1), ncol=2, byrow=TRUE)
cclust(x, centers=x[2:3,], dist="manhattan", method="kmeans")
While this works:
cclust(x, centers=x[2:3,], dist="euclidean", method="kmeans")
I'm posting this here because I am not sure if it is a bug.

cclust - cindex - binary data
Hi,
I'm trying to debug a function I wrote to calculate the cindex for a
hierarchical tree.
For this it is useful to compare my calculations with those in output from
the clustindex function, in the cclust library.
There's no way, however, to have the cindex value for a given output of the
cclust function, as a NA value is always returned.
This happens almost surely because the cindex in

Problems with cclust
To Whom It May Concern,
I am currently trying to use R to perform a "kmeans" clustering of a
three dimensional data set. In the directory
R-1.5.1/library/cclust/data/ I have created a file that
has the following format (only the first few lines are shown for
brevity):

Package cclust error
Hello, here is my problem,
After looking at the mail archives, I found a
description of the error I get when I use this
package.
At first I even tought that they were showing how to solve it.
But the thing is that by saying "the programmer
forgot drop=FALSE" doesn't show me how I should
get rid of the problem
I have looked inside the package very quickly and

R-beta: "cclust" Package
There is a new version of the 'CCLUST' package ,where i removed the extra
command for the kmeans algorithm in the .R programm and also the comments
about it in the .Rd help page. Now in the cclust library the kmeans
algorithm can be applied only by using the cclust function.

cclust args.
hi,
What is the significance of the 2nd arg in cclust, the
'number of clusters'. I have one matrix with two
columns representing x,y coards. I'd like to see how
random the distributions is.
If I try cclust with 'number of clusters' 1 I get
an error, > 1 works though.

Help with CCLUS
Hi,
I am using the following syntax to enter data and perform a cluster analysis:

error-prone feature?
Hi All,
while looking why the cclust(cclust) doesn't work for 1-dimensional data,
I've found unpleasant behavior in semantics of R. Indeed:
is.matrix(matrix(cbind(c(1,2,3,4)),ncol=2)[1:2,]) == TRUE
but:
is.matrix(matrix(c(1,2))[1:2,]) == FALSE
kind regards,

estimating number of clusters ("Null or more")
Hi all,
once more about the old subj :-)
My data has too much various distribution families and for every
particular experiment
I need just to decide whether the data is "quite homogeneous" or it has
two or more
clusters. I've revisited the following libraries:
amap, clust, cclust, mclust, multiv, normix, survey.
And I didn't find any ready-to-use general

cluster indices
Hi-
I'd like to apply some of the cluter indices, using 'clustindex' in the
cclust package, but using output from hierarchical clustering using
'hclust' in the mva package.
The two packages use a different format for storing the results of
clustering; has anyone coerced one into the other?
Thanks!

Clustering and Calinski's index
I have to solve a clustering problem.
My first step is to determinate the number of clusters, that's why I 'm using
the Calinski index ( [tr(b)/(k-1)]/[tr(w)/(k-1)] ) which i try to maximize
to have the best number of clusters.
A function is already implemented in R to calculate this index :
clustIndex(cl,x, index="calinski")
where cl is the result of a clustering method ,

Importing Data.
hi,
I'm a bit new to R and need a hand importing data.
I have a text file of (x,y) pairs like:
x,y
x,y
x,y
I can read them in fine with read.table(), but I need to do some
cluster analysis on them, so I need it in a format cclust will
understand, namely a Matrix. Can anyone help with the code to
to convert the data type?
Thanks,

OK. Thank you a lot. Now patched cclust and clustIndex
work fine for 1D case. BTW, why not to apply the "drop=F"
to these functions? I guess other users need 1D case as
well.
