Oja median
I discovered recently that the phrase "Oja median" produces no hits in
Jonathan Baron's very valuable R search engine. I found this surprising
since I've long regarded this idea as one of the more interesting notions
in the multivariate robustness literature. To begin to remedy this oversight
I wrote a bivariate version and then decided that writing a general p-variate

amap new version (multidimensional analysis)
Dear R users,
Thanks to a new contributor, Luigi Cerulo, amap provides 2 more metrics,
and another agglomeration linkage for distance computation, and hierarchical
clustering.
The new centroid linkage method implemented in the cluster3
software tool (http://bonsai.hgc.jp/~mdehoon/software/cluster/software.htm).
In this method the pseudoitem of a cluster is computed as the average of
the items

amap
Dear R users,
Version 0.7-1 of the amap package has been uploaded to CRAN.
Amap package includes standard hierarchical
clustering and k-means. We optimize implementation
(with a parallelized hierarchical clustering) and
allow the possibility of using different distances like
Eulidean or Spearman (rank-based metric).
We implement a principal component analysis (with robusts

Amap new release
A new major version of Amap package is available on CRAN.
For this major release, all clustering code has been rewritten in C++.
Amap implements several tools in the field of clustering and robust statistics.
New features are:
* clustering possible in float precision (less memory needs)
* new rank-based metric: Kendall distance, use for both matrix distance computation, K-means, and

Runtime Error! Keep on happening while using amap, anacor and ca pckg
Hi there dear R users,
Does anyone have any idea what the following error means and how to sort
it out?
Runtime Error!

amap : hclust agglomeration
Hi,
I'm trying to understand the complete linkage method in hclust. Can anyone provide a breakdown of the formula (p9 of the pdf documentation) or tell me what the "sup" operator does/means?
thanks in advance

About compositional data analysis
The compositional data xi=(x_i1,x_i2,...,x_in), for each fixed i , xij>0,
and sum(xij)=1;
I want to compare the mean( u_i) of several groups
i.e.
H0: u_1=u_2=...=u_N
or
H0: u_11=u_21=...=u_N1
Are there any ANOVA tpye tools to do this work in R?
Thanks,

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.

[PATCH] Fix support for Linux kernel images with no protected mode code
Some kernel images use the Linux kernel boot protocol and header
structure, but do not actually have any protected-mode code. For
instance, grub's 1024-byte lnxboot.img consists of 1024 real-mode bytes
and 0 protected-mode bytes; you can concatenate it with a full grub
core.img to produce a self-contained bootable kernel, but you can also
use it standalone as the kernel with the core.img

how to compute uncentered (pearson correlation) correlation efficiently
Hi,
Seeking suggestions to compute uncentered (pearson correlation) correlation
efficiently.
corr from stats library works on x and y columns. dist from amap library
works on x and y rows.
My data layout is slightly different such that row(i) of matrix x is
compared to row(i) of matrix y.

rcorr.cens Goodman-Kruskal gamma
Dear r-helpers!
I want to classify my vegetation data with hierachical cluster analysis.
My Dataset consist of Abundance-Values (Braun-Blanquet ordinal scale; ranked) for each plant species and relev?.
I found a lot of r-packages dealing with cluster analysis, but none of them is able to calculate a distance measure for ranked data.
Podani recommends the use of Goodman and Kruskals' Gamma for

[PATCH] Extend Multiboot1 with support for ELF64 file format
This patch is just a (shameless) copy from bug #28 [1].
The original patch has been sitting there for a couple of years now,
and it was based on Syslinux v 4.05.
The patch I am posting here is just a re-base on v.6.03. Whichever
inadequate formatting (tabs, trailing spaces...), or any kind of
correction that was required for the original patch to be accepted, is
probably still required now.

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

New package test results available
We've added a column at

these will be updated weekly.
The Sun Studio compiler is that used on Solaris: these runs were on
the Linux version. All the other platforms are using gcc 4, so this
provides an opportunity for checking for use of gcc-specific features

Canberra distance
Hi,
I misunderstand the definition of Canberra distance in R.
On Internet and in function description pages of dist() from stats and
Dist() from amap, Canberra distance between vectors x and y, d(x,y), is :
d(x,y) = sum(abs(x-y)/(x+y))
But in use, through simple examples, we find that the formula is :
d(x,y) = (NZ + 1)/NZ * sum(abs(x-y)/(x+y))
with NZ = nb of pairs of coordinates that are

Configuration questions: 1.9.18p10
I've got 1.9.18p10 up and running happily on a Solaris 2.4 box. I have got
the configuration set so that from my own PC (running NT4, sp4) on the same
subnet, I can login with no problems. Running smbclient on the Unix box
also confirms that I can use other user ID's also.
Problem 1: other users do not seem to be able to login.
