which kernel do people use?
Hi all,
I'm doing a very informal and unscientific poll: which kernel do you use
on your CentOS machines? Not which version of the CentOS kernel, but
which repository. Here are some examples I can think of off the top of
my head:
==CentOS stock
==build own from CentOS SRPMs
==kernel-ml (from ELRepo)
==kernel-lt (from ELRepo)
==OpenVZ kernel
==build own from kernel.org
==other?

Two-node cluster often hanging in o2hb/jdb2
Hi,
I'm pretty new to ocfs2 and a bit stuck. I have two Debian/Squeeze
(testing) machines accessing an ocfs2 filesystem over aoe. The
filesystem sits on an lvm2 volume, but I guess that is irrelevant.
Even when mostly idle, everything accessing the cluster sometimes hangs
for about 20 seconds. This happens rather frequently, say every 5
minutes, but the interval seems irregular while the

Xenial rpart package on CRAN built with wrong R version?
I manually downloaded the rpart package and installed it using dpkg, without removing the old rpart package first, and now everything works. During the installation, dpkg said:
Unpacking r-cran-rpart (4.1-13-1cran1xenial0) over (4.1-13-1cran1xenial0)
So again, it seemed that the new version had been installed, but it really wasn?t. I had no idea that something like this could happen. Huh.

percent sign in plot annotation
Hello,
I would like to annotate a graph with the expression 'alpha = 5%' (the
alpha should be displayed as the greek letter).
I tried
> text(1,1,expression(alpha == 5%))
which gives a syntax error.
escaping the percent sign (\%) or doubling (%%) does not help.
What do I do?
Thanks,

Committing with git
> At the dev meeting I heard Doug Gregor say something like, "what kind of dirty animals are you, you just push directly to master!?" Based on that, I think other communities may set up workflows where they push branches to places, and some automation rebases and updates master asynchronously, optionally conditioned on some (light) testing or approval.

how to make read in a vector of 0s and 1s with no space between them
Hi all,
Probably a rudimentary question. I have a flat file that looks like
this (the real one has ~10e6 elements):
10110100101001011101011
and I want to pull that into R as a vector, but with each digit being
it's own element. There are no separators between the digits. How can
I accomplish this? Thanks in advance!

Ctrl+C in R will terminate the child process which is spawned by using "pipe"
Hi, all,
I pressed Ctrl+C in R process, and found that the child process which was
spawned by using "pipe" is terminated due to this.
Are there any way to work around it, so that the child process can run
happily without being terminated? Or can we block the signal for the child
process?
1. I used pipe to spawn one C++ process, which will running in a loop
without exiting immediately.

chisq.test, basic question
The cells are interpreted as counts, so by scaling you're analyzing a
different experiment (one with fewer observations). So the chi-squared value
will change (the terms (O-E)^2/E in the statistic scale linearly ignoring
rounding and "Yates' continuity correction").
The chisq.test on the original data is a test of association. Conventionally
you decide ahead of time on a

Bug(?) in predict.tree() --- Evaluation order of Boolean operators
Dear R users
I have a problem with predict.tree() when I want the fitted values
of a tree object to be returned (i.e. argument 'newdata' is missing).
Whatever I specify for argument 'type' the fitted model object is
returned.
Example:
library(tree)
data(kyphosis)
fit.tree <- tree(Kyphosis ~ Age + Number + Start, data=kyphosis)
p <- predict(fit.tree,

things that are difficult/impossible to do in SAS or SPSS but simple in R
Hi all,
I'm giving a talk in a few days to a group of psychology faculty and
grad students re the R statistical language. Most people in my dept.
use SAS or SPSS. It occurred to me that it would be nice to have a few
concrete examples of things that are fairly straightforward to do in R
but that are difficult or impossible to do in SAS or SPSS. However, it
has been so long since I have used

skip non-sequential lines using scan?
Hi all,
Is there a way to skip non-sequential lines using the "skip" argument
in the scan function?
E.g., I have a matrix with 100 rows and 1e7 columns. I open a
connection and want to read only lines 5, 7, 9, etc [i.e.,
seq(5,99,2)]
It might seem that the syntax to do this would be something like this

[R-SIG-Mac] How to interrupt an R process that hangs
+1--this is the single most-annoying issue with R that I know of.
My usual solution, after accomplishing nothing as R spins idly for a couple
hours, is to kill the process and lose any un-saved work. save.history() is
my friend, but is a big delay when you work with big data sets as I do, so I
don't run it after every command.
I have cc'd r-help here, however, because I experience this

Google Custom Search Engine for R
Hi,
Since "R" is a (very) generic name, I've been having some trouble
searching the web for this topic. Due to this, I've just created a
Google Custom Search Engine that includes several of the most relevant
sites that have information on R.
See it in action at:
