eval-parse and lme in a loop
Hi everybody,
I'm having trouble getting an eval-parse combination to work with lme in a for loop.
Consider the code below. The call to lme outside the loop works. The call to aov inside the loop works, but the call to to lme inside the loop does not.
The latter fails with

anova and contratst
Hi everybody,
I'm using the gmodels package to convert human readable contrasts
into the format required by R and would be grateful if someone could
confirm for me whether I've got the contrasts right in the sample
code below.
I'm working on the assumption that the contrasts are index according
to the way that levels reports them for a factor.
In my case

allow-query.
Hi,
I am using nsd as my authority-only dns servers and find it fast,
stable, reliable - all of the design goals you set out for, great.
I have a zone that is intended only to be visible to people on my
network. In bind I would enforce this with an 'allow-query'
configuration directive.
I checked the latest 'nsd-for-bind-users' document, and 'allow-query'
is not

subset() multiple arguments
This is what I would like to do and it works just fine. Is there a way to
shorten this code so I don't have to subset a subset of a subset?

Lagrangian=="Yes"), EventType=="Regular")

NoMethodError in Event_type#create
I am new Ruby on Rails, so excuse me if my question seems pretty obvious.
I am trying to validate uniqueness of a filed:
class EventType < ActiveRecord::Base
belongs_to :sport

end
When I run it, I get this error message:

Missing security model in 1.2.8?
I have successfully (I believe) built (rebuilt on Ubuntu 14.04), installed, and used libvirt 1.2.2. Behaviorally I can't tell the difference between what I've built and what Ubuntu distributes.
Specifically, "virsh capabilities" shows this:

Suggesting patch to link DOIs against secure resolver
Dear Madams and Sirs,
because the DOI foundation recommends a new, secure resolver [1], I
wanted to suggest the attached patch. It
a) updates a static DOI link in the docu,
b) the code chunks that generate new ones, and
c) a reg-ex that detects DOI links.
Hopefully, my first venture into SVN & patch files was done correctly.
My apologies, if there is anything amiss. In that case, I'll

simple C function segfaults
Hello,
I use the simplest of examples that somebody can think
of in order to generate a matrix of random numbers
from within C, calling appropriate R functions. The
concrete example is below:

#include <stdlib.h>
#include <math.h>
#include <R.h>

#define COLM( i, j, m ) ( m*j + i)

"too large for hashing"
Hello,
I'm doing some analysis on a rather large data set. In this case,
some simple commands are failing. For example, this one:
> x$eventtype <- factor(x$eventtype)
Error in unique.default(x) : length 1093574297 is too large for hashing
...I think this is a bug, because "hashing" should not be required for the
"factor" function. Am I right? The whole column

Expected pairwise.student.t and TukeyHSD behavior?
pairwise.t.test is returning NAs when one of the samples only has one entry, while TukeyHSD returns results (maybe not trustworthy or believable, but results).
I stumbled on this because I did not realize one of my samples only had one entry while most of the others had several hundred, so I realize this is not a desirable situation. I'm really just curious about the difference between how

HI,
You can do this:

dat.bru<- dat1[!is.na(dat1$evnmt_brutal),]
fun2<- function(dat){?

??? lst2<- lapply(lst1,function(x) x[cumsum(x$evnmt_brutal==0)>0,])
??? lst3<- lapply(lst2,function(x) x[!(all(x$evnmt_brutal==1)|all(x$evnmt_brutal==0)),])

adding text to a plot created with strat.plot() from package rioja
I have a plot created with strat.plot() from package rioja. When
the plot is created with scale.percent=FALSE, each x axes is labeled at
0 and its maximum. However, when scale.percent=TRUE, the x axes are not
labeled. I need to use scale.percent=TRUE and I need labels for the x axes.
I have been able to add labels to the x axes with mtext but it is

recommendation for post-hoc tests after anova
Greetings all,
I've done some ANOVAs and have found significant effects across my
groups, so now I have to do some post-hoc tests to ascertain which of
the groups is driving the significant effect. Usually one would do
something like a Newman-Keuls or Scheffe test to get at this but based
on googling and browsing through the r-help archives R doesn't support
these and they seem to be

variables as arguments in formulae in aov?
Hi all,
I wonder if you could help me with (what is surely) a simple R question?
I've written a simple R script (attached) to perform multiple ANOVAs
on the columns in a table loaded in from a a file (also attached). I
loop through the list of columns for which I want to perform the
ANOVAs, storing the column name in a variable. When I try to perform
the ANOVA using the variable name as a

How to find the root causes of compiler bugs in practice?
Hi, developers,
Recently, I read two papers [1], [2] about finding the root causes of compiler bugs. However, I do not find any information in these paper about how compiler developers find the root causes of compiler bugs in practice. So I am curious whether these techniques are useful in practice. For my experience, the outputs of compilers are always used to isolate the causes of compiler

[PATCH][RESEND] PV drivers for HVM guests
I am enclosing the patch I have been working on. I have tested this on sles9 (2.6.5) and RHEL 4 (2.6.9). The patch applies cleanly on ChangeSet 11635. This patch was cleaned up based on Ian''s and DOI''s work.
