split character string in matrix into character vector and numeric vector
Hello,
I've got a matrix consisting of one column with n rows. Each field in
the matrix is filled with a character vector.
I would like to convert this matrix into a character vector containing
the B03_MAH-type entries from the beginning of each row and a data.frame
that contains the numeric data, but I am stuck.
I have tried to use textConnection with sep = " " but since

About summary in linear models
Hello!!, for linear models fit I use Gretl, but now I'm starting to use R,
I would like to know if is there some function to obtain a extended summary
like in Gretl.
I will write a example in Gretl

Duda sobre summary
Hola!! A ver si alguien puede ayudarme!!
Para ajuste de modelos lineales normalmente uso Gretl. Ahora estoy

que haga un summary extendido como el de Gretl. Os pongo un ejemplo
del summary de Gretl.

Generating Replicate Datasets (using loops or other means)
Hello All,
I have searched many help forums, message boards, etc. and I just can't
apply the comments to what I need my program to do. I am running R 2.5.1 on
an XP system, and my desire is to produce replicate datasets for a
simulation study I am running. Essentially, I have sets of parameters (a's,
b's, and c's) that define a function which produces a decimal value. This

Don't understand removing constant on 1-way ANOVA
I am playing with the a 1-way anova with and without the "-1" option.
I have a simple cooked up example below but it behaves the same on a more
complex real example.
From what I can tell:
1) the estimated means of the different levels are correctly estimated
either way (although reported as means with the -1 and as contrasts without
the -1 as expected)
2) the residuals are

interpretation of F-statistics in GAMs
dear listers,
I use gam (from mgcv) for evaluation of shape and strength of relationships
between a response variable and several predictors.
How can I interpret the 'F' values viven in the GAM summary? Is it
appropriate to treat them in a similar manner as the T-statistics in a
linear model, i.e. larger values mean that this variable has a stronger
impact than a variable with smaller F?

Bug in arima?
I'm using the fixed argument in arima. Shouldn't ar4, ar5, and ar6

Hola Ruben,
Sí precisamente es lo que comentas, en matemáticas no se suele llamar
bucketización (este término se emplea más en informática) sino datos
agrupados. Pero la idea es la que tu mismo dices.
Respecto a las gráficas que has puesto, me han aclarado mucho sobre el
tema, gracias.

Post-hoc tests in MASS using glm.nb
I am struggling to generate p values for comparisons of levels (post-hoc
tests) in a glm with a negative binomial distribution
I am trying to compare cell counts on different days as grown on different
media (e.g. types of cryogel) so I have 2 explanatory variables (Day and
Cryogel), which are both factors, and an over-dispersed count variable
(number of cells) as the response. I know that both

Column-mean-values for targeted rows
Hi all,
I'm handling massive data.frames and matrices in R (30000 x 400).
In the 1st column, say, I have 0s and 1s indicating rows that matter; other columns have probability values.
One simple task I would like to do would be to get the column mean values for signaled rows (the ones with 1)
As a very fresh "programmer" I have build a simple function in R which should not be very
