Novice question about getting data into R
I found it easy to use R when typing data manually into it. Now I need to
read data from a file, and I get the following errors:

Why isn't R recognising integers as numbers?
I have a number of files containing anywhere from a few dozen to a few
thousand integers, one per record.
The statement "refdata18 =
read.csv("K:\\MerchantData\\RiskModel\\Capture.Week.18.csv", header =
TRUE,na.strings="")" works fine, and if I type refdata18, I get the integers
displayed, one value per record (along with a record number). However, when
I try "

Applying an R script to data within MySQL? How to?
I am trying something I haven't attempted before and the available
documentation doesn't quite answer my questions (at least in a way I can
understand). My usual course of action would be to extract my data from my
DB, do whatever manipulation is necessary, either manually or using a C++
program, and then import the data into R. Now I need to try to do it all

R-help Digest, Vol 67, Issue 23
Warranty on Accuracy, Precision, Legality, ... of R in Research
(These questions may well have been raised.)
What is the implied warranty of using R for research & publications, consulting, etc.?
Alternately, how does one obtain such a warranty?
Your answers will be much appreciated.
Perhaps you can point me to some websites which discussed this subject in the past.
Thanks & regards

Questions and a blockpull issue
Coming off of xen environment; still testing with kvm, just a few
questions:
1. What is the roadmap for release of qemu-kvm 1.1 and libvirt 0.10.2 for
el6, cause I had to compile from upstream to get the latest stuff.
2. Should not virt-manager show the sparsed disk size instead of actual
reserved size of a vm?
3. Where is the virsh bash_completion conf.d file from upstream; since el6

Risk differences with survey package
I'm trying to use the survey package to calculate a risk difference with
confidence interval for binge drinking between sexes. Variables are
X_RFBING2 (Yes, No) and SEX. Both are factors. I can get the group
prevalences easily enough with
result <- svyby(~X_RFBING2, ~SEX, la04.svy, svymean, na.rm = TRUE)
and then extract components from the svyby object with SE() and coef() to

how to list and kill existing console sessions to VMs?
Hi everyone,
If a VM is configured to have a console attached to it, like using
http://libvirt.org/formatdomain.html#elementCharConsole
Libvirt offers access to VM serial console's using the virDomainOpenConsole API[1]
However, I didn't find a way to
1. list the existing connections to the console
2. kill an existing connection - without reconnecting using VIR_DOMAIN_CONSOLE_FORCE[2]
