ctree question
Hello. I have used the "party" package to generate a regression tree as
follows:
>origdata<-read.csv("origdata.csv")
>ctrl<-ctree_control(mincriterion=0.99,maxdepth=10,minbucket=10)
>test.ct<-ctree(Y~X1+X2+X3,data=origdata,control=ctrl)
The above works fine. Orig data was my training data. I now have a test

Creation of additional image within a domU
Chaps,
Perhaps this question is a little basic for this list but I''m not
really sure of the simplest method or best tool for the job.
I''ve created some images with `dd=/dev/zero ....` and I''m using them
for the domUs now. Some of them have been running for a few months
with no probs. Trouble is that I''d like to create a separate partition
within the domU.

R-beta: losing attributes in binary ops
Thanks to Thomas Lumley for the very quick fix of the NextMethod(.Generic)
bug. The patch enclosed in his message to r-help fixed that problem
nicely.
But..., I've got another one.

attr(x,"foo") <- "bar"
attributes(x < 4)
returns NULL.
The "foo" attribute has been lost in the "x < 4" operation.

Puppet in a virtual environment
Morning chaps,
From my understanding the puppet master must have a hostname of
"puppet". Is this correct? I''d like to be able to call this box
whatever I like. I think that I can do that within

kickstart + domU for static IP
I've set up a local webserver to store kickstart files for domUs. All
parameters are respected apart from the network settings. DomU always
gets DHCP. Can any one help to unwrap this one? Does one add hostname,
ip, netmask and gateway values to the /etc/xen/blah.cfg file?

Hello there
This is the first time I have used r-help message board so I hope I have got
the right address.
I am trying to check the residuals of a GLMM model(run using the package
lme4). I have been able to check the residiuals of REMLs in lme4 using the
following:

Audio from fifo
My first guess about the problem would be that the programs want
to process the stuff in a different order, e.g. mplayer wants to
output some sound before anymore video and encoder_example wants

depend on the order of stuff in the file mplayer is reading.
I guess something similar could happen for opening the pipes as
well.
