smbclient recursive get skips files (rarely)
We seem to have stumbled onto an intermittant bug using smbclient
to retrieve files from a W2000 server. Every so often it just
ignores some files on a recursive mget. When it ignores files
it always ignores the same files. The exact same command
repeated again may (or may not) pick up that file. Running a DIR
on the directory in question shows the same defect, sometimes the
cursed file is

Statistical analysis of a large database
Deall all,
We need to perform a statistical analysis of a large database (40,000 entries with approximately 500 fields in each entry) currently handled in Oracle. The data contains categorical variables only.
At the current stage we suggest classification and clustering analysis.
We are planning to perform the analysis in R and would be very grateful for any

R tutorial
Dear all,
I have just found a 'good' tutorial R for datamining. I think it
should be on the contributed docs.
http://cran.r-project.org/other-docs.html
Here is the link
http://www.liaad.up.pt/~ltorgo/DataMiningWithR/
What do you think?
Kind regards
Christophe

R as a non-functional language
I'm reading Torgo (2010) *Data Mining with
R*<http://www.liaad.up.pt/~ltorgo/DataMiningWithR/code.html>in
preparation for a class I'll be teaching next quarter. Here's an
example
that is very non-functional.
> pH <- c(4.5,7,7.3,8.2,6.3)
> names(pH) <- c('area1','area2','mud','dam','middle')
> pH

Help with objects
Hi all,
I would appreciate some help in understanding how to find out about objects.
For example, to the extent that I understand R it seems to treat everything
as an object even without declaring them as objects. Everything has
attributes, for example, which are like instance variables in objects. In
addition, there are S3 and S3 category objects. Is there a good
introductory description of how

R & DataMining
Dear R-user,
I wish to know if someone is using R as concern
Datamining or KDD (Knowledge Discovery in Database)
and if already exists a R package specialized in this
kind of analysis.
I found this contributes on the R web site:

Begginer with R
Hello all,
Im just beggining using R. I have read a couple of introductory documents
but they are very general. Is there a document focused on classification?
(this is what Ill be using R for). Examples would be just fine.
Thanks in advance,

Neural Net forecasting
Are there any packages in R that are suitable for doing time series
forecasting using neural networks? I have looked in the nnet package and
neural package and they both seem geared towards classification.

Importing big plain files from ERP-System/Data Mining with R
Hi,
how can I import really big plain text data files (several GB) from an
ERP-System (SAP-Tables) to R?
The Header of these files are always similar, for example:
Tabelle: T009
Angezeigte Felder: 7 von 7 Feststehende F??hrungsspalten: 2 Listbreite

About building R1.6.1 on Cygwin
Hello.
For building REmbeddedPostgres in Omegat
project(http://www.omegahat.org/RSPostgres/) requiring PostgresSQL's libs,
I've tried to build R1.6.1 on Cygwin following the instruction of

PhD student reading list, suggestions wanted
I've got a PhD student starting this year.
She'll be working on data mining.
She has asked for a reading list while she's still in her home
country, which is a really good sign.
Her cosupervisor and I don't (think we) have any problem with
choosing things that are specifically about data mining, but
there are some statistical ideas (sampling, exploratory-vs-confirmatory,

Query about creating time sequences
Hi All,
I have a query about time based sequences. I know such questions have been
asked a lot on forums, but I couldnt find the exact thing that I was
looking for.
I want to create a time-based sequence which will mimic the trading window
AND would span multiple days. Something like below:
"2011-01-03 09:15:00 IST"
"2011-01-03 09:15:01 IST"

Simple encodig sample...
Hi all.
I'm Mat & I'm new :)
I'm testing libtheora + libogg perhaps for a commercial product.
I started watching encoder_example.c ... I simplified it for testing
it easier.
It seems ok to me but I have no experience with theora so I would like
to know if my code is correct.
I tried to debug it with Valgrind and I found 4 possible memory leaks...
but I think they can be
