Hack Attack: Moving domU''s between hosts without shared disk
So I have two hosts that I want to move domU''s between, but they do
not have any shared disk. I am willing to suffer some downtime to move
the domU''s, but not a lot (like maybe the time needed to do a reboot,
but certainly not the time required to copy the virtual disks over).
This is what I did.
WARNING: THIS IS A HACK AND YOU SHOULD BE CAREFUL DOING THIS.
But it worked for me

prediction in a loop with only one sample
Dear all,
I have a sample with 920 observations. I want to create a loop which takes
300 of these observations for the prediction and the rest to estimate the
model.
My idea was to create something like this:
cs.training.dat <- read.table...
cs.training.dat_sub1 <- subset(cs.training.dat, Income>10)
cs.training.dat_sub2 <- subset(cs.training.dat_sub1, Dept.Ratio<=1)

MCMC coding problem
Dear All,
I am trying to convert some S-plus code that I have to run MCMC into
R-code. The program works in S-plus, but runs slowly.
I have managed to source the program into R. R recognizes that the program
is there; for example, it will display the code when I type the function
name at the prompt. However, the program will not run. When I try to run
the program, I get the following error

aggregate slow with variables of type 'dates' - how to solve
Dear all
I use aggregate with variables of type numeric and dates. For type numeric
functions, such as sum() are very fast, but similar simple functions, such
as min() are much slower for the variables of type 'dates'. The difference
gets bigger the larger the 'id' var is - but see this sample code:
dts <- dates(c("02/27/92", "02/27/92",

Fwd: Recall function: "evaluation nested too deeply: infinite recursion / options(expressions=)?"
hello all
i searched the archives and couldn't get a solution to the following question.
i have the following function:
F=function(z,v)
{
if (v==-.5) return(1) else return(2*v/z + 1/Recall(z,v-1))
}
and while testing whether it works (ie F(z,v) is approx = besselK(z,1+v)/besselK(z,V). the recursion formula allows one to calculate besselK(z,1+v)/besselK(z,V) for large values of z )

ogg123 remote interface
Hi,
I've been working on ogg123 to see if i could add a remote interface
compatible with the one in mpg123. This remote interface is used mainly by
mp3 players which use mpg123 as their backend.
The reason i did this was that i have recently encoded some of my cd's in
ogg vorbis format but wanted to keep using my favourite player (playmp3list,

ogg123 --end 1:59 patch.ogg
Hi
Here is another patch regarding time in ogg123 which is more
controvercial than the other one I send some days ago. (see
attachment)
When working with Daisy/SMIL [1] files it would be helpfull if the
user could stop play at a specific time. Currently .ogg files are not
allowed in the Daisy format but that will hopefully happen one day if
I work hard at it.

vfs_gpfs module errors

I'm encountering an error with some of my Windows clients when
using CTDB and samba to access a GPFS hosted share. We see the following

About qvalue
Hello,
I'm apologize to have made failure before.
I wrote this : p<-scan("teststat.txt") on R and R returns Error in scan
("teststat.txt") : "scan" expected a real, got "x". I don't really
understand,because teststat has been created, so........
Thanks a lot.

Kalman Filter
Hi,
I am studying Kalman Filter and it seems to be difficult for me to apply the
filter on a simple ARMA.
It is easy to construct the state-space model, for instance:
dlmModARMA(ar=c(0.4,-0.2),ma=c(0.2,-0.1, sigma2=1)
but applying the dlmFilter on it, it doesn't work...
I don't know if my problem is clear but if anyone has already worked on
Kalman filter, it could be great to advise me!

C++ dev
Hello,
I wish to use R functions in a C++ programm.
I have installed D COM Server but with this application i think it isn't possible to acces mouse event..., is it true?
My second idea is to compile libraries which are used, but i haven't source code, and the libraries existing are compiled under unix, but i'd like have .lib and .dll
Thanks for your informations

Our team at IITH have been experimenting with loop-distribution pass in
LLVM. We see the following results on few benchmarks.

Average R-squared of model1 to model n
Hi,
We got a question about interpretating R-suqared.
The actual outputs for a test dataset is X=(x1,x2, ..., xn).
model 1 predicted the outputs as Y1=(y11,y12,..., y1n)
model n predicted the outputs as Y2=(y21,y22,..., y2n)
...
model m predicted the outputs as Ym=(ym1,ym2,..., ymn)
Now we have two ways to calculate R squared to evaluate the average performance of committee model.

Hello every GNU's,
I have a question about mt.plot, on multtest package.
I'm wondering how do a plot with test like bonferroni, holm, hochberg,... and
also résults of SAM(Significiance Analysis Microarrays) as we can see on
several document of Sandrine Dudoit.
Thanks a lot and Have a nice day
