STI, controllers and views
Hello,
I have set up that uses single table inheritance. I have a number of
model subclasses following the example in AWDWR that uses Manager <
Employee < Person.
First question. Do I need to create controller classes for each? I
don''t think I do because a single controller should be able to shunt the
data between the models and the views.
Second question. Say I have a view

Total response file count limited to 21
Actually, sorry, my fix was for the case where you had other arguments beginning with @ that weren't response files, whereas yours has actual response files, so my patch won't help there. CCing Reid and Hans, who did a bunch of the implementation in this area.

Trouble with drplot
Hi, I am a newbie with R, so I hope my question isn't too stupid. I am trying to generate dose-response curves using the "drfit" package. I have formatted my CSV files to the correct format, and have no trouble running drfit to get a summary of my data. The problem is that when I try to use "drplot" to graph my data I get an error. The message is:

Interesting behavior of lm() with small, problematic data sets
I've recently come across the following results reported from the lm() function when applied to a particular type of admittedly difficult data. When working with
small data sets (for instance 3 points) with the same response for different predicting variable, the resulting slope estimate is a reasonable approximation of the expected 0.0, but the p-value of that slope estimate is a surprising

acts_as_list and single table inheritance
in a single table inheritance model, rails will automatically set the
scope for acts_as_list to the ''type'' field as well as any other scope
conditions we provide.
Is there a way to disable this? i want to use STI but I want
acts_as_list to disregard the class type when getting/setting
positions.
thanks

Using acts_as_list, acts_as_tree, and STI in one model
Check it out y''all:
http://rafb.net/p/NJg5U147.html
(pastie was down)
I''m trying to make a tree which belongs_to another model, where you can
have sections or items as children, and sections can have sections or
items as well. Moreover, any siblings should be sortable.
For instance:
Root
- Section 1
- - Item A
- - Item B
- Item C
- Section 2
- - Item D

Confusion over syntax in a package
Hello,
I am new to R and I am attempting to use the ProbForecastGOP package
for some research I am conducting.
The package works fine when I call the functions from the command line
as the examples instruct.
However, I am attempting to step through some of the functions so that
I can obtain a better idea of what is going on. I have come to the

Difference between rake test:units and individually running ruby -I test test/unit/something_test.rb ?
Here''s my issue: running ruby -I test test/unit/something_test.rb for
each of my unit tests works perfectly.
However, running rake test:units brings errors in all of them - some
object becomes nil for some reason.
Why might this be happening?
Specifics: the object that is successfully not nil when I run the unit
tests one-by-one but becomes nil when I do rake test:units is defined

Odd error: Physical size does not match superblock size
Hello, I had something interesting happen on a RH8 ext3 system I setup.I
am at a loss to understand what happened.
Info:
This system has two IDE disks, partitioned identically, and the largest
partition on each (/dev/hda3 and /dev/hdb3, 96GB each) was mirrored in a
linux software RAID-1 configuration.
It was running fine for many months. Then I updated the kernel and
needed to reboot accordingly.

Write/Display AR query as Grouped Results?
I''ve got a publications table that contains an author_id foreign key and
a pubrole_id foreign key. What I want to do is query the DB using AR so
that I can get a list of all publications that belong_to a particular
author, and group the results by the pubrole.role_name (Author, Joint
Author, Editor, etc.) so that the results look something like:
Author

book2 info

How to plot linear, cubic and quadratic fitting curve in a figure?
Hi R experts,
Could you please help me to fit a linear, cubic and quadratic curve in a figure? I was trying to show all these three fitting curves with different colour in one figure.
I spent substantial time to figure it out, but I could not.
I have given here a example and what I did for linear, but no idea for cubic and quadratic fitting curve

Total response file count limited to 21
IMO, a limit of at most 20 nested response files would make a lot more
sense than 20 total response files. I don't think the total should really
have a limit at all.
Since we expand the files in place while iterating over the arglist, we'd
need to keep a separate array listing the end-offset of each file we're
currently nested within, and update the offsets with every expansion of

Bypassing automatic STI generation
Hi,
Let''s say I have the following:
Product < AR
Memberships < Product
I know that the product with id 10 has its type column set to
"Membership", but still I''d like to treat it as a regular product.
So if I do: Product.find(10), Rails returns a Membership object.
Is it possible to tell rails to not care about STI and to simply return
a Product object?

Count entries in postgresql grouped by date
Hi!
I have a table with visits with a visited_at: attribute which is a datetime
field. They seem to be stored as UTC. Now I want to count all visits each
day and return something like:
{
2013-01-01: 8,
2013-01-02: 4,
2013-01-07: 9,

}
So, I did it like this which kind of works...:
