randomForest: more than one variable needed?
Hi,
I am doing feature selection for my dataset. The following is
the extreme case where only one feature is left. But I got
the error below. So my question is that do I have to use
more than one features?

Random Forest:how to do an automatic rerun using only the important variables
Hi,
I am using the Random Forest Package, and want to do an automatic rerun
using only those variables that were most important in the original run.
Is there anybody who has experience with this and can give me helpful
suggestions?
Best regards,

Error in names(x) <- value: 'names' attribute must be the same length as the vector
Dear R-helpers,
I am stuck on an error in R: When I run my code (below), I get this error
back:
Error in names(x) <- value :
'names' attribute must be the same length as the vector
Then when I use traceback(), R gives me back this in return:

some question regarding random forest
Hi,
I had two questions regarding random forests for regression.
1) I have read the original paper by Breiman as well as a paper
dicussing an application of random forests and it appears that the one
of the nice features of this technique is good predictive ability.
However I have some data with which I have generated a linear model
using lm(). I can get an RMS error of 0.43 and an R^2 of

SeDiskOperatorPrivilege and 2012 R2 domain
Tim,
Thanks for the hint. Usermap for root applied, locally made requests fail
now systematically with
"Could not connect to server <server address>
Connection failed: NT_STATUS_LOCK_NOT_GRANTED"
It is kind of improvement :) Random things scare me.

Marc,
Thanks for your help and clarifications. I was indeed addressing the domain
controller (2012 R2) due to my misunderstanding. Addressing the request at
the file server (Samba 4) to the file server fails too but with different
errors. Rights list succeeds.

Re: Reg: Adding "edu" device using XML file
Hello Han,
Thanks for the response. The XML option with qemu:commandline works if the
device is added during the VM creation. But I would like to hot-plug the
device to the running VM. I can add the device using the command line
<virsh qemu-monitor-command --hmp VM-Name device_add edu,id=edu0>
But I would like to add the device using the XML file, like <virsh

Can RH AS3 be a ADS member with winbind+nss+krb5?
Samba is trying to be a member server in an AD in native mode, using
winbind, nss, and kerberose. There are 3 kdc's (2 are Win2003, 1 is
Win2000), samba server is RH-AS3 + Samba version 3.0.9 (from samba.org)
+ krb5 1.3.1-6 (from Fedora Core). I thought I had things working (join
succeeded, could access shares, modify files), and then it stopped
working. After clearing out the host account

Improve hot cold splitting to aggressively outline small blocks
Hello,
I am Ruijie Fang, a GSoC student working on "Improve hot cold
splitting to aggressively outline small blocks." Over the course of
last week, I met with my mentor and co-mentor, Aditya Kumar, and
Rodrigo Rocha, and we made a preliminary plan on improving the
existing hot/cold splitting pass in LLVM through identifying patterns
of cold blocks in real-world workloads via block

Where can I find the slirp-helper?
For the libvirt 5.8 release, I find that there is a new comment in
qemu.conf:
#slirp_helper = "/usr/bin/slirp-helper"
It indicates that there is a slirp-helper to help setup slirp network. But
I cannot
find it even after I built the latest qemu(v4.1.0-1378-g98b2e3c9ab) and
libvirt
(v5.9.0-rc1-2-g73f91d659b).
Could you please tell me where I can find that helper program?
Thanks

Improve hot cold splitting to aggressively outline small blocks
Hi Teresa,
Thank you for your reply! I discussed this with Aditya and Rodrigo today
about this. We will always have PGO turned on for our benchmark, (i.e. we
assume the profiling information is always available). In terms of the
workload we supply to PGO: For postgresql, I suggested we use the "pgbench"
benchmark, a TPC-B-based SQL benchmark for postgres, to supply profiling
information

circular correlation
I have a problem that deals with correlating wind velocity to seed
collection data. The problem lies in that I have a wind data set that
is contains 2000+ data points and weed collection data on the order of a
couple hundred. Both data sets were collected for the same time period,
but there is not a one-to-one wind velocity->seed location match. My
understanding of correlation is that you

Unable to get virtual users set up with database auth
I can't seem to get imap virtual users to work with database
authentication on new Scientific Linux 6.5 server with Sendmail 8.14.4 &

Apparently I have to also create system users because
sendmail/procmail/dovecot want to check directory ownership.
So I created a database, made entry for the user, created the user

Dial plan questions
I'm afraid I'm quite confused by what I've found on the Wiki.
I have the following dial plan that works:
exten => 2201,1,Dial(sip/2201@gs1.uucp,20,)
exten => 2201,2,Voicemail(u2201)
exten => 2201,3,Hangup

exten => 2201,104,hangup
When the phone is in use it goes to voice mail as busy. When not
picked up, as
