Hi all,
I realized what I was doing wrong and aplogize about posting before thinkg
about it for long enough. If I try to plot the pca results directly
(bulbil.pca), I can't do it. But if I extract the axes 1 and 2 and plot
directly, I can add col=as.numeric(group.bulbil[,3]) to the text()

hello,
thanks a lot for your help.
@ Stephen: In my opinion the proscrutes rotation is more used to
compare the
alignment of different ordination methods. But maybe I'm wrong.
@ Bill: Thanks for the comprehensive description.

I've been using R for many years and have always tried to keep my R

I don´t know if I got what you are looking for.
But see the code below.
x-1:100
y-x+(runif(100)*x)

my.coefs-coef(mymod)
my.coefs

Hi R users,
I am trying to do two-way clustering (using information of both observation and
variables). Is there any package available in R.
Another querry, if somebody can provide related information (website) regarding
this statistics, it will be great.
Thanks in advance.
Regards,

Hi Erika,
I have not tried this before, and I hope that somebody will correct
me if I'm wrong, but the glmer function in the lme4 library appears to do
what you want. From examples(lmer):

Hi,
How can I make the cor(x, y, method=spearman) call to produce an
error when the input to it (x, y) produces an error? Here is a simple
example:
a - c(0, 1, 2)
b - c(100, 2, 4)
## error:
log(a)
[1] -Inf 0.000 0.6931472
## error, as expected:
cor(log(a), log(b), method=pearson)

As a side note, in (some versions of) S, due to partial matching,
binomial(log) is valid -- it just does logistic regression.

Hi all,
I've uploaded STAR (Spike Train Analysis with R) on CRAN two days ago.
The package is designed to analyze neuronal spike (action potential)
trains. It uses S3 classes and methods and makes heavy use of other
CRAN packages like gss, R2HTML, mgcv, survival.
