Clusteranalysis Chi-square test and SingleLinkage
Hi
The short version of my questions is this:
How can I run a chi-square test over a matrix (table) to get the distanaces
between rows and then run a SingleLinkage (or other fusion algorithm over
the resulting table?

PAM authentication failure?
Howdy:
Can anybody explain why /var/log/messages is filled with the
following?
Aug 18 09:37:53 rama PAM_pwdb[28483]: 1 authentication failure;
(uid=0) -> arnold for samba service

Corregir mismo ID para individuos diferentes en una serie temporal
Hola,
Antes de nada, muchas gracias por tu ayuda.

very sophisticated but because of that somewhat unfathomable at times.
Simplified:
I want to exclude directories named no_bak anywhere in the tree
but only the files under them, not the direcrories themselves.
My exclude rules look like:
no_bak/*
/no_bak/*
The first one does catch directories by that name on the first level

Howto: Mac OS X to Windows VM
Hi,
I have a mac pro and a windows Vm which I want to keep sync. I tired

Indexing multi-dimensional table
I want to take slices of a multi-dimensional table (or array) without

do.call(`[`, list(tbl, x,NULL,NULL)]
where I built the list on the fly. It works great as long as I only want the
first dimension however when I try a different dimension, say with
list(tbl,NULL,x,NULL), I get
