Windows binary for R 1.6.1 FIXED
To Windows R users:
The binary build of R that I uploaded on Tuesday contained errors in
the compiled HTML help files and some of the PDF versions of the
manuals. In particular, the index was missing from the CHM files, and
the table of contents was missing from at least one of the manuals.
I've since found the error in my setup, and have rebuilt the
distribution. I uploaded it to CRAN

question about AIC
Please, forgive my ignorance on statistics, but I have a rather simple
question concerning AIC. Small values of AIC mean good fit of the model. How
about negative values of AIC? Is a model with AIC=0.5 considered to have
better fit than a model with AIC=-500?
I couldn't find anything explaining this in the documentation or any
elementary statistics textbook that I have at my disposal.
Thanks

R-patched for Windows
I've put up a build of the current R-patched (and updated recommended
packages) for Windows at
http://www.stats.ox.ac.uk/pub/bdr/RWin/Rpre/SetupRpatched.exe
This should be able to rename files on Win 9x (unlike the mid-May build)
and can build packages accessing Rblas.dll.
As ever, this is less tested than an official release, in particular only
on Windows XP, but ought to have fewer

Extracting elements from an reStruct
Sorry if this is obvious, but my S skills aren't great and I haven't been
able to find it documented anywhere.
I want to write a new function for use with lme objects; the function will
simply calculate an ICC (aka "rho") for each level of a mixed-effects
model. What I need for this is pretty simple:
(c(var1..varn, residual)) / sum(c(var1..varn, residual))
where var1..varn

Background color(s) for groupedData plot
I've been using par() to check the graphics parameters
associated with both plot(<fitted linear model>) and
plot(<grouped data object>). AFAIK the only differences
are in the $cxy, $usr, $xaxp, and $yaxp parameters but
the background color for the grouped data plot is grey
while the linear model plot has a white background.

problem with boot
Hello R-users,
I'm using the boot's library. I have two questions:
1. I execute for example
data<-rnorm(100)
boot(data,mean,500)
and I obtain 500 equal bootstrap samples of data. Why?
2. I need to calculate the bootstrap confidence intervals for a statistic,
but when I use the function boot.ci it shows the error message:

How to extract R{i} from lme object?
Hi, lme() users,
Can some one tell me how to do this.
I model Orthodont with the same G for random
variables, but different R{i}'s for boys and girls, so
that I can get sigma1_square_hat for boys and
sigma2_square_hat for girls.
The model is Y{i}=X{i}beta + Z{i}b + e{i}
b ~ iid N(0,G) and e{i} ~ iid N(0,R{i}) i=1,2
orth.lme <- lme(distance ~ Sex * age, data=Orthodont,

combining vectors to matrices or data frames
hi,
during a for(i in 1:xx]) loop I always newly calculate a vector
(e.g. tmp<-c(a,b,c,d,e) )
now i need that vector to be attached at the bootom of a matrix (or
data.frame).
e.g.
m<-matrix()
for(i in 1:5]){
#some calculations for a,b,c,d,e
a<- ... b<- ... c<- .. ....
tmp<-c(a,b,c,d,e)
??? now I need to attach this tmp to the matrix m ???
}
