Odd behaviour with scale()
Moi!
A student here has been getting a bit irritated with some side effects
of scale() (OS is Windows XP, the behaviour occurs in R 2.0.0, but not
1.7.1). The problem is that she scales a variable in a data frame, then
does a regression, and tries to get some predictions for some new data.
However, at this point she gets an error (see the example below). This
seems to be because the

Converting characters to numbers in data frames
I'm sure I'm missing something obvious here, but I can't find the
solution (including in the FAQ etc.).
I have a vector of names of variables like this: NRes.x.y. where x and y
are numbers. I want to extract these numbers as numbers to use
elsewhere. I can extract the numbers as a list of characters using
strsplit(), and convert that to a data frame, e.g.:

Substituting vectors into a legend
I have a simple (!) problem. What I want to do is to create a legend with
Greek letters, and substituting numbers into the legend. Like this:
mu=1:3
Mean=rep(mu, each=20)
plot(runif(60), rnorm(60,Mean,0.1), pch=Mean) # create a plot
legend(0.6,1.7, paste("mu =", 1:3), pch=mu)
but with a Greek letter mu.
I think the solution has something to do with substitute() possibly along

Odd behaviour of step (and stepAIC)?
I can only assume I'm betraying my ignorance here, but this is not what
I would expect.
I'm getting the following from a stepwise selection (with both step and
stepAIC):

Start: AIC= 593.56
sqrt(Grids) ~ SE + Edge + NH

Population simulation.
Hello,
can anyone tell me if R has any special function for simulating the structure
of human populations? Something like the genetic algorithm?
I need to simulate a sample of a population with a specific structure. Is
there something on R that can help me?
Thanks to everyone.

Problem with Integrate
The background: I'm trying to fit a Poisson-lognormal distrbutuion to
some data. This is a way of modelling species abundances:
N ~ Pois(lam)
log(lam) ~ N(mu, sigma2)
The number of individuals are Poisson distributed with an abundance
drawn from a log-normal distrbution.
To fit this to data, I need to integrate out lam. In principle, I can
do it this way:
PLN1 <- function(lam, Count,

A log on Bayesian statistics, stochastic cost frontier, montecarl o markov chains, bayesian P-values
Dear friends,
Over the past weeks, I have been asking a lot of questions about how to
use R in Bayesian analysis. I am brand new to R, but I am very pleased with
it. I started with winbugs but I found winbugs to be a limited software, not
bad but has several limitations. By contrast, R allows the analyst to tackle
any problem with a huge set of tools for any kind of analysis. I love R. In

arguments imply differing number of rows
4000:6000 gives you 4000, 4001, ..., 6000. I suspect you want
population= c(seq(4000, 6000, length=5), seq(3500, 4300, length=5),
seq(3000, 3200, length=5))

Dear all,
I have several questions regarding fisher.test() in
R, and I'd highly appreciate any help with it.
I have a group of observations, each having people's
income, and an indicator of whether selected in or out

income of people who are in and out.
Because the distribution is far from normal, I decide

Openbugs and rbugs on mac with wine
Hello list,
I?ve been trying to get OpenBUGS running on my mac using the wine
emulator. I can run Openbugs just fine by doing:
wine ~/OpenBUGS312/OpenBUGS.exe
In the terminal, so OpenBUGS works. When I try to run the schools
example using rbugs(), the OpenBUGS process starts in wine, but it
just sits there, no log, no script, no output of any sort. The rbugs

Are they fully identical: WinBUGS and OpenBUGS; R2WinBUGS and R2OpenBUGS
Hello ALL!
I am running Linux, Fedora 15 64-bits, and R on it. I need to use
WinBUGS and R2WinBUGS, but as far as I read, WinBUGS is closed project,
to be continued with/as OpenBUGS. Thus, I have found R2OpenBUGS on
OpenBUGS Contributed Code (http://openbugs.info/w/UserContributedCode),
not on CRAN. Author(s) states that it is equivalent for R2WinBUGS. I
tried briefly, and realized few minor

R, Coda, and OpenBUGS
Hi All,
I am trying to figure out how to use R-Coda with the output from
OpenBugs. I have installed and loaded the packages BRugs and R2WinBUGS.
I have successfully run a simple Bayes model in WinBUGS using R2WinBUGS'
"bugs" and have used "read.bugs" to build the coda object. I can
successfully switch to OpenBugs and run the same model and get the basic

Makefile for embedding OpenBUGS in R package
Dear list,
I'm trying to embed OpenBUGS in an R package for use of it
on 64-bit Linux. In order to get the CLI working one has to
compile C code contained in $OpenBUGS/Manuals/CBugs.html
(copied to say CBugs.c) using
gcc -m32 -o bugs CBugs.c -ldl
I put the OpenBUGS distribution in the ./inst subdirectory of
the package root. Where should I now put the CBugs.c and how

binary form for Windows and will be synced by the mirrors shortly.

Cannot start OpenBUGS from R2WinBugs
Hello,
I'm running R version 3.4.2 on Windows. I have a program written in
BUGS which I can successfully run from the R2WinBUGS package.
I would also like to try and use the same package to use OpenBUGS
(version 3.2.3) rather than WinBUGS.
The initial output looks ok (shown below), but the OpenBUGS executable
is never started. Instead I see a process running called
?BugsHelper.exe *32? in
