Scaling in SVM
Dear Community!
I'm using the svm method of package e1071 for classifying my data. This
really works fine, but however I have to work after creating the support
vectors and the parameters with unscaled data. So the problem is when I try
to train the classifier with the option "scale=F" the result is quite poor,
so training with scaled data is essential. The rescaling of the support

svm regression in R
Hallo,
I have a question concerning SVM regression in R. I intend to use SVMs for feature selection (and knowledge discovery). For this purpose I will need to extract the weights that are associated with my features. I understand from a previous thread on SVM classification, that predictive models can be derived from SVs, coefficiants and rhos, but it is unclear for me how to transfer this

Plotting LDA results
Dear Users!
I think I still have some problems in understanding LDA and the methods of
plotting the results.
The case is the following: I'm having a dataset containing two classes where
each datapoint has 19 dimensions. Training with lda(...) works fine, and I'm
getting 19 LD coefficients. So far so good. Now I want to visualize the
result, and here is where my simple knowledge ends. What

SVM linear kernel and SV
Dear all,
I'm a trainee statistician in a company and we'd like to understand svm
mechanism, at first with simple examples.
I use e1071 package and I have several questions. I'm working with data
extracted from cats data (from R). My dataset corresponds to a completely
separable case with a binary response variable ( Sex with 2 levels: F and
M), two explanatory variables (Bwt

samba 3.0 pdc and samba 2.2.8a password authentication failure
Hi list,
I have the problem, that a samba 2.2.8a server cannot validate the
password with a samba 3.0 pdc for a client request. A samba 2.2.1 works
fine. Let me explain the situation in more detail:
samba 3.0 pdc machine a
samba 2.2.8a server machine b (doesn't work)
samba 2.2.1 server machine c (works)
samba 2.2.8 client machine d
Machine b and c should authenticate the passwords

Group member can not delete files - only dir (775) owner can
Hi there,
I have a problem I can not solve myself.
I have samba 3.0.28 installed on a Ubuntu 8.0.4 server.

Support vector in lcrabs example
Can anyone explain the root of my problem?
When I type the following code into R, I receive 42 support
vectors insted of the 21 stated in the book 'Modern Applied
Statistics with S':
library(MASS);
library(e1071);
library(class);
lcrabs <- log(crabs[,4:8]);
(svm(crabs$sp ~ ., data = lcrabs, cost = 100, gamma = 1));
By changing the value of gamma I can obtain only 21 support vectors,

Correction, _you_ expect! Very few computer programs do that. You
cannot `require' two digits by options(digits=2): ?options says

Samba suddenly not working, and all I did was change hard drives!
Hi,
We've had our business server functioning dandy for a long time, with
SAMBA acting as a domain controller for our Windows XP pro clients. No
issues. All was lovely. We're running Suse 9.3, Kernel
2.6.8-24.14-smp, Samba version Version 3.0.9-2.3.
Now, it was time to upgrade hard drives in the RAID controller, to
create a 200 gb container (rather than the 100 gb container we had).
So,

How to interpret and modify "plot.svm"?
Dear R people,
I am trying to plot the results from running svm in library(e1071). I
use plot.svm. After searching through the help archives and FAQ, I
still have several questions:
1. In default, crosses indicate support vectors. But why are there
two colors of crosses? What do they represent?
2. I want to draw a white-gray colored plot and modify the different
colored crosses or circles by

Hoaglin Outlier Method
I am a new user of R so please bear with me. I have reviewed some R books,
FAQs and such but the volume of material is great. I am in the process of
porting my current SAS and SVS Script code to Lotus Approach, R and

My question is, can you help me determine the best R method to implement
the Hoaglin Outlier Method? It is used in the Appendix A and B of the fo

SVS tree lists
I know this is a long shot, but does anyone out there have code for converting a R-dataframe into a Stand Visualization System (SVS) tree list? It would save me a bit of time.
I would be interested if anyone has FVS code as well. I will be working (reworking) NE-TWIGS equations to a regionwide dataset.
Thanks in advance,

R_using non linear regression with constraints
I ran the following script. I satisfied the constraint by
making a*b a single parameter, which isn't always possible.
I also ran nlxb() from nlsr package, and this gives singular
values of the Jacobian. In the unconstrained case, the svs are
pretty awful, and I wouldn't trust the results as a model, though
the minimum is probably OK. The constrained result has a much
larger sum of squares.

Is "samba3_vscan" compiled anymore, by anyone?
I'm looking at the RPM's over at http://ftp.sernet.de/pub/samba/3.5/,
and noticing that the "samba3-vscan" package is not being built for
any OS. Is this deliberate? If so, perhaps it can be deleted from the
SRPM? It no longer builds correctly for Samba v3.5, and is a years old
virus scanning tool in any case. It's therefore probably unsuitable

HTML-documentaion on NT
Once you hae in stalled Guido's NT port of R it
is nice and easy to install the add-on packages too.
However, it would be nice to have links to the documentation
of the functions in all the packages from the "All Installed
Functions" html-page, and not have to go through each of
the packages.
Is there a utility somewhere to do this?
