Network issue in dom0
Hello,
I have a network issue in dom0; I''m not sure if it''s a configuration
problem or a design problem in my setup.
My setup:
The server (dom0) runs Ubuntu 7.10, Xen was installed using apt-get
(means version: Xen 3.10, Kernel 2.6.22-14). This server has 4 NICs. I
use bridged networking with my own script which creates 4 bridges
("$dir/network-bridge"

non linear regression with R
...aks !) that I would
like to fit with a function which look like this:
p(a,b,x,y)=b/(2*pi*a?gamma(2/b))*exp(-(square_root(x?+y?)/a)power(b))
I am looking for a and b values that fit my data at best.
Can someone give me hints to perform such an analysis with R ?
Thanks a lot

conditional selection with Factors
...r in "[.data.frame"(use, use$month == levels(use$month)[1]) :
undefined columns selected
It seems if a logical variable is created, and the subsetting on a factor variable won't work directly.(It works directly for numeric variables)
Can anyone help please.

History of R
...e the most is why is R as an open source
project is so incredibly successful and other projects, say for example,
Octave don't enjoy that level of success?
I have some ideas of course, but I would really like to know your
thoughts when you look at R from such a vantage point.
Thanks.

customizing help()
...ve the following error:
Error in help(topic, package = .packages(all = T), lib.loc = .lib.loc, :
No documentation for `topic'
I tried also with
> my.help
function(x){
help(x,chmhelp)}
with the same result.
Only doing help(help) is working. Why my function doesn't work?

Axes in 3D plots
I am wondering if anyone knows how to change or rotate the default axes on a 3D scatterplot. I would like to change which sides of the cube the 3 axes are displayed on.
Many thanks,

Samab and init.d
...ing in initd, or to use the script, much like
the one provided by SuSE. ?? so far I have used the script, but I don't
like the fact of having to start samba manually. I would much prefer to
see it run as a service. just to confirm all it really involves is starting
smbd and nmbd

Samba and /etc/shadow.
Dear mailing-list!
I have Samba 2.0.6 on a Redhat 6.1 linux box.
How can I make samba use the /etc/shadow file
for authenticating users?
Reading the archives I assumed there should be
a compile-time option I should set, but I found
no such option.
Regards

dont' have access to my smb.conf

Samba device that integrates Pc and Apple Networks
...ly it was a small box that had a samba server built in. you would
connect your mac to it with the
other side connecting to the hub of a pcnetwork. It would intern allow
Apple shares to be viewed in network
neighborhood, and macs to mount pc shares./ does this ring a bell with
anyone.

Create factors in R for more than one variable
...read in the data.
The problem is that factors isn't created automatically, because the data is coded numerically.
To make factors out of the 50 questions I must do:
V1 <- factor(V1)
I don't want to do it 50 times. Is there a quicker way without using loops?
Thanks
