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?

The long-version of my question:
My data consists of different data of different countries so I have stuff
like how many people can read, write in X,Y,Z countries

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
Aug 18 09:38:25 rama PAM_pwdb[28494]: (login) session opened for
user arnold by arnold(uid=0)
The first one happens every time I browse to rama from win95
Explorer; the second one is from a telnet login

reading large data sets
I have some difficulties in reading big dataset; I have to import a dataset with 1'661'852 observations saved in a 51.4Mb - txt file.
I was wandering if this is a memory size problem or if I realy can't import such big datasets.
If the memory allocated to my R is not enough, I would like to know exactly which comands I should use in order to read and use my large dataset.

Efficient lookup on a two-dimensional table
Dear R-Users,
I need to lookup values from a 2-d table using the row names and column
names as indices. I was wondering if there's a way to do this without an
explicit loop.
Example:
#x is the 2-d table that holds the values
x <- matrix(rnorm(26*12),nrow=26)
rownames(x) <- letters
colnames(x) <- month.name
#y is a data frame that has the "keys" I want to use as indices

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
using other Sync programs but they do not seems to be working. I tend
to leave applications running which create their own temp files in its
own specific folder, which caused the other sync programs to crash. I
tired SyncToy by MS and Unison. I am looking for a bi-directional sync

calculating correlation of a Supply/Demand measure and price change (in high frequency time series data)
Regarding "financial" data: I have a high frequency (1 minute) measure of
supply/demand and I'd like to know if it has any influence on short term
price changes (also 1 minute).
Question: How do I calculate the correlation between this supply/demand
measure and price changes (correctly)?
Some facts about that data:
The price changes and supply/demand measure are non-normal. An

creation of an high frequency series
Hi R Users!
I would like to create an high frequency series but I am experiencing some
difficulties.
My series should start at 09.30 a.m. each day and end at 16.00 for, let's
say, 2 years. I don't care on how many observations are for each day. It's
ok also one observation each minute. In this case, I would have 390
observations each day.
I have tried the following:

High frequency time-series
Having to collect hourly electricity loads and quarter-of-an-hour electricity production data for some years I think that the tidiest way of doing it is to resort to ts but I don't know how to define such a frequency starting from a set date.

Creation of Domain- and PDC-SID in samba

just a question to understand
we have a NT PDC and i successfully transfered it's data to samba 3.0

Thanks - I already have the Ogg Vorbis encoder (oggenc.exe).

Tildes en Slidify
Hola a todos.
Estoy creando un documento con Slidify y me surge un problema con las
letras con tildes que no me las reconoce y en su lugar pone un signo
de interrogación.
He probado a poner R-Studio por defecto en UTF-8 y en Windows-1252 y
tengo puesto como diccionario principal es español. Nada de esto ha
funcionado.
¿Alguien ha usado este paquete y ha conseguido solucionar este problema?
