overlay multiple time series on one plot
Hello,
I have four different time series from the same time period within a
year (February through August) but they are from different years. I can
not figure out how to plot them all (so they will be overlayed instead
of plotted on after another) on the same graph with the x-axis
corresponding to the month/day instead of year/month/day.
Thank you.

Dear all,<?xml:namespace prefix = o ns = "urn:schemas-microsoft-com:office:office" /><o:p></o:p>
I would like to generate a contour-plot according to a master plot. The problem is that the rainbow-palette included in R does not answer this purpose. I need a darker blue, no turquoise, relatively less green, more yellow and more red. Haw can I adjust

Multichannel Speex
Hello!
The question is: "Does Speex support multiple channels?"
Speex is reported to encode only mono and stereo signals.
But I found 'nb_channel' defined in <speex_header.h> among the Public
Attributes.
Does this mean that it is also possible to store more than two channels in
one single speex-file?
Maybe it will be possible in the next future...?
TIA

Pivot without copy
Hi,
Is it possible to "pivot" to a new image without doing blockcopy or
blockpull? I know how to use snapshots and blockpull to create a new image
and pivot to using it live, but what I would like to do is to have a VM
switch from using imageA.qcow2 to image2.qcow2 while running. I don't see
why this wouldn't be possible since some of the existing libvirt tools can
do this when

Force parent window
Does Wine allow me to change the parent window of an application run under Wine?
I've tested one of the 64k demos from Farbrausch (http://www.farb-rausch.com/) and it works perfectly under Wine. I'd like to have them running as my wallpaper.
I've tried Xwinwrap but it doesn't work so I was wondering if there is something I can pass to Wine to tell it to draw its windows on the

Re: Pivot without copy
Hi Eric,
Thanks for the info. I see the value in this, but it isn't quite what I was
looking for. Basically what I want to do is to switch between snapshots
quickly. For instance, I am currently working on designing a HA SQL
implementation with failover. So right now I have 5 VM's running postgresql
as a replication group. I am trying a lot of different things and often
have to take a

virsh blockcommit fails regularily (was: virtual drive performance)
Hi,
a small update on this. We have migrated the virtualized host to use the
virtio drivers and now the drive performance is improved so that we can see
a constant transfer rate. Before it used to be the same rate but regularly
dropped to a few bytes/sec for a few seconds and then was fast again.
However we still observe that the following fails regularily:

follow-up on qr.coef bug (PR#8478)
The bug I submitted yesterday (It's not entered in the bug data base, so
I have no ID for it) included a suggested fix that
is not correct. It worked for the examples I gave because there was no
pivoting in fact, or only pivot permutations that were
idempotent. A correction that works in general on the examples I gave
makes these two changes in qr.coef():
## coef[qr$pivot, ]

Question on the idiom: start <- coef; start[fit$pivot] <- coef
I wonder if someone could explain how the following R idiom works (it's
used in
glm.fit).
start <- coef
start[fit$pivot] <- coef
coef is a vector of coefficients, set by .Fortran("dqrls", ...).
fit$pivot is a vector of integer indexes (indicating how dqrls permuted
the columns
of x). If coef has n elements, fit$pivot is a permutation of seq(1,5).
start[fit$pivot]

Equivalent of Excel pivot tables in R
Can somebody tell me how to do the equivalent of a pivot table in R ?
For example, if I have :
var1 var2 var3
a x 10
b y 20
a z 10
b z 20
a z 10
b z 20
I could have :
x y z
a 1 0 2
b 0 1 2
where entries in the table are counts of var3.

typo or stale info in qr man
man for `qr` says that the function uses LINPACK's DQRDC, while it in
fact uses DQRDC2.
```
The QR decomposition of the matrix as computed by LINPACK or LAPACK.
The components in the returned value correspond directly to the values
returned by DQRDC/DGEQP3/ZGEQP3

recovering from deleted snapshot
I have an automatic process setup. It's still pretty new and obviously
in need of better error handling because now I find myself in a bad state.
I run snapshot-create-as across all my vms, then do zfs replication to
the target backup system, then blockcommit everything.
virsh snapshot-create-as --domain $vm snap --diskspec
$DISK,file=$VMPREFIX/"$vm"-snap.qcow2 --disk-only --atomic
