Interpretación de salida de un GLM
Estimada comunidad, tengo unas dudas que son muy básicas creo, pero es mi
primera incursión en GLM.
Estoy ajustando un modelo binomial a unos datos de germinación. El modelo
es muy sencillo, tengo un factor "Condicion" con dos niveles: "a" y "b"
(nivel de humedad en suelo). Por otro lado, tengo una variable explicativa
"HF" (horas frío=estratificación) que

Rcmd check for Windows fails (PR#7369)

Version: 2.0
OS: Windows
Submission from: (NULL) (80.202.87.143)
Dear R core
Thanks again for a superb program. This is really one of the rare instances I
find a bug. The bug is easy to bypass, but can be quite confusing;
"Rcmd check" seems to fail without any good error report if the package contains
a certain amount of R code and is run from a

windows oddity related to alternate data streams
Hi all,
I was just looking into what was causing the lag when I open my samba
(3.0.27a) shares from windows (XP, SP2).
strace showed that directories were being opened and closed a lot, in
sequence. Playing with Process Monitor suggests windows is trying to
create alternate data streams on for the directory entires: it does a

Overriding validation?
Is there a "normal" way to override the behavior of validator methods
(like validates_presence_of) for updates vs. creation? For example,
in the AWDR example store program, the User class validates the
presence of the password and its length - which makes sense when the
user entry is created. But what if you wanted to provide an update
form that updates just certain items

Check if current route == some route
I have a before_filter in ApplicationController in which I want to check
if the current location is the same as a certain route, so that I only
redirect non-logged in visitors to the "join" page if they''re not on
that page already.
The code I came up with is a bit ugly:
redirect_to join_url unless (@logged_in or action_name == "join")

Can we do GLM on 2GB data set with R?
We are wanting to use R instead of/in addition to our existing stats
package because of it's huge assortment of stat functions. But, we
routinely need to fit GLM models to files that are approximately 2-4GB
(as SQL tables, un-indexed, w/tinyint-sized fields except for the
response & weight variables). Is this feasible, does anybody know,
given sufficient hardware, using R? It appears to

Error in linearHypothesis.mlm: The error SSP matrix is apparently of deficient rank
Hi,
I have encountered this error when attempting a One-way Repeated-measure ANOVA

I have read the "Anova in car: SSPE apparently deficient rank" thread
by I'm not sure the within-subject interaction has more degrees of freedom
than subjects in my case.

Smal problem with porting code to S-PLUS (PR#871)
Full_Name: Harald Fekjær
Version: 1.22
OS: Windows
Submission from: (NULL) (158.36.132.220)
Dear R developers
Actually, this is not a bug, but a small remark about a way R is working that
makes trouble in porting the code to S.
If I run the following i R:
---
midl <- 4
attr(midl,"Object created") <- date()
dump("midl","midl.R")

Data Manipulation Question
Can R support data manipulation programming that is available in the SAS datastep? Specifically, can R support the following:
- Read multiple dataset one record at a time and compare values from each; then base on if-then logic write to multiple output files
- Load a lookup table and then process a different file; based on if-then logic, access and lookup values in the table

compilers for R on AMD64
Dear R-devel,
A while ago Prof. Ripley had mentioned that g77 on AMD64 isn't the greatest,
and the Salford Fortran is likely to be better. My question is, has anyone
tried compiling R with Salford compilers (or other commercial compilers)?
If so, do they offer performance advantages over GCC?
TIA for any info.
Best,
Andy

lme, lmer, convergence
Hello, all,
I am running some simulations to estimate power for a complicated epidemiological study, and am using lme and lmer to get these estimates. I have to run a few thousand iterations, and once in a great while, an iteration will create fake data such that the model won't converge. I see from Google searches that this is not an uncommon situation.
My question: is there a way to

A Tribute to my Great Grandmother (Off Topic)
I realize this is off-topic, but I need to post it.
I had to go up to Connecticut on January the 12th quite unexpectedly
because my great-grandmother Ethel, someone I was very close to, died
that morning, at 93 years old. She was an incredible woman. I was
asked to be one of the pallbearers.
Her ultimate goal in life, and one she fulfilled every day, was to

Error with mongrel_rails start
When I make an empty Rails web application, and go through the steps
to create/include a database, and scaffold, mongrel_rails start (or

pre-existing web app and I got some errors.
First, I gathered the app''s folder (checked the contents, it has all
the folders plus one extra: components) and placed it under ruby/
