R helps win competitions
DeaR ComRades,
This is a quote from a News article in Science's 11-February issue, about competitions to model data:
"For Chris Raimondi, a search-engine expert based in Baltimore, Maryland, and winner of the HIV-treatment competition, the Kaggle contest motivated him to hone his skills in a newly learned computer language called R, which he used to encode the winning data model.

Plotmath: suprscript on scalable delimiter?
ComRades,
How do you put a superscript on a scalable delimiter?
I want to put 'b' as the power of the expression in the following plot:
t <- 1:25
K <- 0.2
y <- ((1-exp(-K*t))/(1-exp(-K*t)*exp(K)))^3
plot(t,y,"l",main="K=0.2, b=3")
text(15,5,expression(bgroup("(",frac(1-e^-Kt,1-e^-Kt*e^K),")")))
Plotmath examples in demo(plotmath) do not

How to make a table of a desired dimension
Hi ComRades,
I want to make a matrix of frequencies from vectors of a continuous
variable spanning different values. For example this code
x<-c(runif(100,10,40),runif(100,43,55))
y<-c(runif(100,7,35),runif(100,37,50))
z<-c(runif(100,10,42),runif(100,45,52))
a<-table(ceiling(x))
b<-table(ceiling(y))
c<-table(ceiling(z))
a
b
c
will give me three tables that start and end at

symlinks
I'm trying to sync a tree containing symbolic links to files outside
that directory tree. I've tried with -L and --copy-unsafe-links but
apparently the files pointed by symbolic links are always re-copied
over and over again regardeless whether they have been modified or
not.
I can hardly believe this is feature, but if this is the case, what
combination of options would let me copy

Using lme() for split plot
Hi,
I'm trying to figure out how to use lme() for analyzing a split-plot
experiment. I've been looking at the examples from the 'R Book',
those are nested but with only one factor at the whole-plot level, my
test is 2^2 at the whole-plot level, with a single many level factor
at the sub-plot level. My question is about properly specifying the
random effects part of the model,

Strange error message from geoR´s likfit () lik. max. func.
ComRades:
I am geeting the error message
Error in ldots[[which(MET)]] : attempt to select less than one element

geoR.
I have tried with old data for which likfit() successfully maximised the
likelihood in previous versions of geoR, and yet the current version
fails.

Tinn-R RGui Send problem
ComRades,
On a recent Windows XP system that I have to use at work, I installed Tinn-R 2.3.4.4 and R 2.10.1
When I mark-select a piece of code, say
summary(x)
written in Tinn-R and send it to the RGui using the send button, the RGui console instead of showing me my piece of code, it shows something like
source(.trPaths[5], echo=FALSE, max.deparse.length=150)
The code is executed fine but if

How to draw partial grid in plot for spatial-binomial experiment?
DeaR comRades:
I have a 2D spatial binomial process as shown in the data and code below.
I am plotting the number of trials and the number of successes in the spatial
binomial experiments and would like to draw the spatial cells were the trials
and successes were counted, i.e. a partial grid in the plot only for those
cells where there is a number. The cells are 2x2 km cells. The count of

Covariance of beta and lambda in geoR likfit
Greetings comRades:
Has anyone worked out a procedure to calculate the estimated covariance
between the beta and lambda estimates in the likelihood-based
geostatistical model implemented in package geoR? If so, please help me
out by letting me know.
Do I have reasons to expect that this covariance term would be big or
perhaps more happily, that it could be discarded without much effect?
