Hi,
I would like to generate a correlation matrix with a
particular structure. For example, a 3n x 3n matrix :
A_(nxn) aI_(nxn) bI_(nxn)
aI_(nxn) A_(nxn) cI_(nxn)
aI_(nxn) cI_(nxn) A_(nxn)
where
- A_(nxn) is a *specified* symmetric, positive
definite nxn matrix.
- I_(nxn) is an identity

Hi All,
I've recently dusted off my cross-compiling hat and decided to add R to the
OpenEmbedded build environment (this is used to build the
OpenZaurus/Familiar distributions for the Zaurus/iPAQ amongst other things -
I note there's also work underway to add the Psion 5mx etc. to
OpenEmbedded).

Extending what Gabor and Peter have already said, the following
should provide a partial solution:
patternCor3 - function(A=diag(2), a=1:3){
# nk x nk covariance correlation matrices
# k = length(a); abs(a) = min(diag(A)
minV.A - min(diag(A))
if(any(adj.a - abs(a)minV.A)){

why is it that i cannot open html help pages out of the R menu? here is what I do: using browser firefox1.0 (open

Dear List,
I have acquired a new desktop and wanted to put a free OS on it. I am trying
Fedora Core 1, but not sure what the best Linux OS is for using R 2.0.1?
Thank you in advance for your input,

Hi,
I've updated the page with the US election maps, now using white
instead of purple for counties that are 50/50 (thanks to Gregoire
Thomas for the code). I like this graph, it relays the information a
lot better. (Note that New England's missing counties are white as
well.) I also removed

Havent seen anything on R-devel yet on this topic, but if the elseif statement
on line 43 of seq.default was
else if (length.out == 0)
double(0)
instead of

numeric(0)
then that *might* satisfy Richard A. O'Keefe's comment for length=0:n cases
Dear R users,
I need to rename the columns of a series of data frames. The names of
the data frames and those of the columns need to be pulled from some
vectors. I tried a couple of things but only got errors. What am I
missing?

I was using 'object.size' to see how much memory a list was taking up.
After executing the command, I had thought that my computer had locked up.
After further testing, I determined that it was taking 241 seconds for
object.size to return a value.
I did notice in the release notes that
Do you know if R has any multiv. Newton-Raphson routine implemented?

Not only does it have R 2.0.1, but it's got a whole bunch of other programs
already installed, including emacs, TeX, kile, and many more apps.
It's debian and based on clusterKnoppix.
You can run it live or install it to hard

Consider using R and take a look at the SNOW package.

We don't have daylight saving anymore,(the running joke here is that it
fades the curtains too quickly) and it's been that way for at least a
decade. So I don't think there are any missing rules.

There is a problem with Fedora core 3 on HP nx500 laptop. The display

I will take care about DST in Australia for the next Rmetrics release.

Hello sir:
As to the variance stabilization method which is applied in the vsnpackage
under R environment,here's a question about the ratio of the 2 channels:
After applying vsn,we can get new_cy5 and new_cy3 intensity according to the
original cy5 and cy3 intensity respectively. And the new_cy5
I'm attempting to do model selection with AIC, using a glm and a lognormal
distribution, but:
fit1-glm(BA~Year,data=pdat.sp1.65.04, family=gaussian(link=log))
## gives the same result as either of the following:
fit1-glm(BA~Year,data=pdat.sp1.65.04, family=gaussian)
Benjamin,
A couple of points:
fit - glm(y ~ x, gaussian(link = log))
does NOT fit a model with a lognormal response distribution. It fits a
non-linear regression model with an ordinary gaussian response
distribution. This model has constant variance, whereas the lognormal
model (which you

Hi,
recently, i installed Gentoo in addition to SuSE on my Laptop.
In order to see whether it was worth the effort, i did a small
benchmark for R under SuSE and Gentoo.
I guess, that the benchmarks under SuSE are also approximately
valid for other binary distributions.
As a consequence,
