Cosinor
Hola, ¿qué tal?:
Tengo la siguiente duda:
Para el caso del Cosinor Simple:
Y = M + A * cos(2*pi*t/T + phi) + error
Cuando T conocido, podemos asumir:
Y = M + beta * X1 + gamma * X2 + error,
siendo X1 = cos(2*pi*t/T) y X2 = sin(2*pi*t/T)
En este caso (Cosinor simple) el modelado lo llevo a cabo del siguiente modo:
lm( y ~ X1 + X2)
Para el caso de componentes múltiples:
Y = M + ?Aj *

Cosinor Analysis
Hola,
En el contexto del método del cosinor descrito por Halberg y posteriormente por Bingham, no logro calcular el error standard correspondiente a la amplitud y a la ortofase. La función lm permite obtener, entre otros datos, el error standard correspondiente a los coeficientes de la regresión (intercept, beta y gamma), pero no sé cómo relacionar ese s.e. de beta y gamma con el s.e. de

Cosinor en R
Hola a todos,
es la primera vez que escribo a la lista, espero explicarme correctamente.
Trabajo en cronobiología de mamíferos y quiero comenzar a analizar mis datos
con R (haciendo análisis de varianza ya llevo unos años en el entorno). Me
interesa saber si cada una de mis variables podría ajustarse a una función
sinusoidal; tengo medidas cada dos horas para cada una. Querría extraer el

Newbie question: 28000+ files for 25000+ records?
Hi
Obviously my question is, is that normal? To have so many files? I was
indexing 6 string fields from 25000+ model records (all of the same
model). The index appears to be working. I guess I was expecting a few
hundred files after optimzing, not more files that records indexed.
Please understand I am brand spanking new to Lucene, Ferret, and AaF.

[ActsAsFerret] OpenSolaris (TextDrive) indexing issues
Gents,
I successfully installed AAF on my TextDrive OpenSolaris Container, but
I''m having some issues with indexing.
I have a model called Blogs which has AAF enabled.
The first time I tried to find_by_contents for a ''word'' I know was on
the Database I got now results. Apparently the index was not ready yet.
Then I waited a few hours and checked that the /index

IFELSE across large array?
Dear all,
As our previous email did not get any response, we try again with a
reformulated question!
We are trying to do something which needs an efficient loop over a huge
array, possibly functions such as apply and related (tapply,
lapply...?), but can't really understand syntax and examples in
practice...i.e. cant' make it work.
to be more specific:
we are trying to apply a mask

Indexing problem 10.9/10.10
Sorry if this is a repost- I wasn''t sure if the www.ruby-forum.com
list works for postings.
I''ve been having trouble with indexing a large amount of documents(2.4M).
Essentially, I have one process that is following the tutorial
dumping documents to an index stored on the file system. If I open the
index with another process, and run the size() method it is stuck at

matrix bands
Dear R developers,
I was looking for a function analogous to base::diag() for getting and
setting bands of a matrix. The closest I could find was Matrix::band(),
but this was not exactly what I wanted for two reasons. Firstly,
Matrix::band() returns a matrix rather than just the specified band.
Secondly, Matrix::band() cannot be used for setting the values for a
matrix band.
Setting or

Assignments inside lapply
Dear all I would like to ask you if an assignment can be done inside a lapply statement.
For example
I would like to covert a double nested for loop
for (i in c(1:dimx)){
for (j in c(1:dimy)){
Powermap[i,j] <- Pr(c(i,j),c(PRX,PRY),f)
}
}
to something like that:
ij<-expand.grid(i=seq(1:dimx),j=(1:dimy))

Rjava, RImageJ, and/or S4 question.
I am out of my league with this question. The following code starts the java imaging program ImageJ from within R, and displays an image (assuming ImageJ is installed on your computer).
library(RImageJ)
img <- IJ$openImage( file.choose() ) #pick an available .tif file
img$show() # make the image object visible
# An image is now displayed
# find out about the objects involved

Recommendation on a probability textbook (conditional probability)
I need to refresh my memory on Probability Theory, especially on
conditional probability. In particular, I want to solve the following
two problems. Can somebody point me some good books on Probability
Theory? Thank you!
1. Z=X+Y, where X and Y are independent random variables and their
distributions are known.
Now, I want to compute E(X | Z = z).

Términos cronobiológicos (Fuera de tema, disculpadme)
Hola a tod@s:
Tengo una duda que no es relativa a R en sentido estricto, aunque sí al fin para cuya persecución he necesitado utilizar R.
Veréis: me gustaría averiguar la diferencia (si existe) entre los términos Cronobiometría y Ritmometría. ¿Alguien lo sabe o puede indicarme alguna lista de correo o referencia bibliográfica que me sirva de apoyo?. La única referencia que encontré es ésta:
