If you do not supply an explicit data list, the jags.model() function
will try to get the data from the calling environment. This is

Hi Bill,
Without an example dataset it's hard to see exactly what you need to
do. But you can get started by looking at the documentation for the
reshape function (?reshape), and by looking at the reshape package.
The reshape package has an associated web page

is what you are searching for.

par(bg = white)
boxplot(x, col = white,
notch=T,medcol=black,whiskcol=white,boxfill=TRUE)

stuck after I identified the probesets with significant changes. I have
problems in assigning probeset specific gene names as well as getting the

Yes, basically. The package title is analysis of complex survey samples, and
the book is a guide to analysis using R, and

LS,
How large a dataset can glm fit with a binomial link function? I have a set
of about 100.000 observations and about 8000 explanatory variables (a factor
with 8000 levels).
Is there a way to find out how large datasets R can handle in general?
Thanks in advance,

How do I fit a mixed effects model with two crossed random effects for grouped

I tried coxme with no luck.
Suppose that y is survival time, uncens is censoring indicator, trt is

ran.eff1 and ran.eff2 below are two crossed random effects. This way, it

Hi R-users:
Can anyone give an example of giving starting values for MCMCglmm?
I can't find any anywhere.
I have 1 random effect (physicians, and there are 50 of them)
and family=ordinal．
How can I specify starting values for my fixed effects? It doesn't seem to have
the option to do so.

Hi,
Does R have a Decision Tree functionality akin to 'Precision Tree' by
Palisade? When I search, I end up with 'rpart' but this does not

Hello Dear,
I am trying to generate samples by using Monte Carlo simulation. For
example,
1000 samples, Exponential distribution (f(x), lambda=0.0005, 0=x=360)
Is there any package for Monte Carlo or just use random sample generation
function?
Many thank you for your help in advance,
