bigglm() results different from glm()
Dear all,
I am using the bigglm package to fit a few GLM's to a large dataset (3
million rows, 6 columns). While trying to fit a Poisson GLM I noticed
that the coefficient estimates were very different from what I obtained
when estimating the model on a smaller dataset using glm(), I wrote a
very basic toy example to compare the results of bigglm() against a
glm() call. Consider the

bigglm() results different from glm()
Hi Sir,
Thanks for making package available to us. I am facing few problems if
you can give some hints:
Problem-1:
The model summary and residual deviance matched (in the mail below) but
I didn't understand why AIC is still different.
> AIC(m1)

> AIC(m1big_longer)

Problem-2:
chunksize argument is there in bigglm but not in biglm, consequently,

split a character variable into several character variable by a character
Dear Mao Jianfeng,
"r-help-owner" is not the place for help, but:
r-help at r-project.org
(CC-ed here)
In any case, strsplit() does the job, i.e.:
> unlist(strsplit("BCPy01-01", "-"))
[1] "BCPy01" "01"
You can work with the whole variable, like:
splitpop <- strsplit(df1$popcode, "-")
then access the first part with

MLE in R
Hi, dear R users
I am a newbie in R and I need to use the method of meximum likelihood to fit a Weibull distribution to my survival data. I use "optim" as follows:

My question is: how do I setup the constraints that the two parametrs of Weibull to be pisotive?

read.table: aborting based on a time constraint
Hello ?
I am trying to write code that will read in multiple datasets;
however, I would like to skip any dataset where the read-in process
takes longer than some fixed cutoff. A generic version of the function
is the following:
for(k in 1:number.of.datasets)
{
X[k]=read.table(?)
}
The issue is that I cannot find a way to embed logic that will abort
the read-in process of a specific dataset

I''m not finding any guidance on this problem. When I try to talk to my

Any help or guidance would be greatly appreciated.

Potential minor GUI bug
Is this an interface bug? Using RGUI for windows I run into a "Not

Navigation techniques, everyone?
I''m rewriting the code to my first app. I want to reuse a lot of it,
but tidy it up a lot. The first thing I will tackle is my nav-bar.
Throughout a user''s experience on my app, I want it to reload as little
as possible (I''ll have about 7 or 8 controllers with about 70 actions).
So, I''ve thought of a few ways of doing it, and was wondering if you

Problem with gettext and functional tests
Hi,
I am using gettext to let my web application know several languages. All
works fine, but since I integrated it, my functional tests don''t work any
more.
I keep getting the error message:

All right, TestRequest doesn''t have a cgi method. Therefore I just included

Where to put code - controller or model
I have a Rails app that is a directory indexer. It passes the desired
directory path in the url.
There is a user table, and a permissions table (which contains the
volumes each user has permission to see). There is also a volume table,
which contains the available volumes, and a path table, which contains
the paths to every file available on the machine. [There are other
tables, but these

Saving boolean attributes
Hi,
I''m just learning Ruby on Rails and ran into something where I know I''m
either doing something very stupid or I''m missing something.
My model as a boolean attribute called active_flag. In my Sql Server
database this is stored as a bit value. I then setup a method in my
controller called "deactivate". This is very simple, it does:

self organizing map advice for categorical data
Hello,
Could anybody offer any advice about implementing a Kohonen self organizing map for categorical data? Specifically I am wondering if there are any pre-existent packages that can deal with categorical data and/or how one would compare the input vector of categoricals with the self organizing map nodes.
Thanks in advance.

Functional Tests misbehaving with Globalize

Apologies to the folks subscribed to the globalize list for dual

I''ve got a project running globalize and rails 1.1.4, and I''ve only
recently adopted a strong love for testing. Now my models are 100%

Accessing form field contents
I have an HTML form on the screen, that is connected to a database
(standard Ruby way). I found that there are people that would rather not
fill in this information, but would rather search Amazon for the info.
Therefore, I added a link to the right of one of the fields that, when
pressed, will search Amazon for what ever you typed into that field.
So, how can I do that? At first I tried

I''m having difficulty figuring out the ruby neccessary to do this so I
thought I would try the list. I''m hoping to get a date_select to only

avail.
