Fuzzy searching
Hi, everyone,
Just wondering if someone had come up with a good way to do fuzzy
searches if you use MySQL as your database (we tried switching to
PostgreSQL, but that ended up adding even more problems). Ferret sounds
great, but reading through the discussion it looks like we need to solve
the problem of write conflicts. I just wrote a post in ruby-talk about
using KirbyBase maybe to solve

best way to combine results from two tables
I want to combine a selection of data from two tables and display it as
list. Note that this isn''t a join.
i''m looking for something like this:
Table 1: Sheep
Name, Age, Farmer, etc. (sheep specific columns)
Table 2: Cows:
Name, Age, Farmer, etc. (cow specific columns)
For my display I nneed something like this:

:include breaks has_many :order
It would appear that using :include on a model that has_many with an
:order on another model makes it so that the order is ignored. Is this
supposed to happen? Strikes me as odd behavior.
For example
class Farmer < ActiveRecord::Base
has_many :cows, :order => ''position''
end
class Cow < ActiveRecord::Base
acts_as_list :scope => :farmer
end

Difficulty in caper: Error in phy$node.label[which(newNb > 0) - Ntip]
Hello,
I'm doing a comparative analysis of mammal brain and body size data.
I'm following Charlie Nunn and Natalie Cooper's instructions for

I run into the following error when I create my comparative dataset,

Changing font in boxplots
Hi all,
I am very new to R and this might be a simple question but I have looked
everywhere you suggest before writing to you.
I am trying to change font type from san-serif to a serif (Times New
Romans) on all labels and axis of my boxplot. I have used this function in
other plots before, e.g.:

Create values based on a table of conditions
Hi R help forum,
I have a simple data frame of four columns - one of numbers (really a
categorical variable), one of dates and one
of data. I have over 500,000 data points to work with, spread over 40
files, each named after a different animal.
These are contact data recorded by proximity loggers over two years
between the animals of the file name and
collars being worn by other animals. The

create matrix
Hi all,
I have a dataset consisting of 5 columns and over 5000 rows. Each row
gives information about an individual animal, including longevity, i.e.
at what age an animal died.
For the model I use I need to create n rows for each animal, n being its
longevity, and a new column 'survival' with a binary 0/1 outcome. When
an animal died e.g. at age 5, there have to be 5 rows of identical

How about a mascot for R?
R users,
How come R doesn't have a mascot? Linux has one and so does LaTeX, so shouldn't R? I personally think that associating a "friendly face" with R would be a good thing for R (one letter names can be quite intimidating).
I apologize if this is addressed in the FAQ. I searched the FAQ as well as the mailing list archives and checked
?mascot
but to no avail. ;-)

accessing current factor in tapply
G'Day,
I want to access in a function called from tapply the current factor. In
my example below, all I want to do is to write the current factor on each
histogram. Needless to say my example does not work. I would be grateful
for pointers in the right direction.
Many thanks

Multilevel modeling of animal behavior
Hello all,
My question is how do I write a multilevel regression model of individual responses to environmental predictors that accounts for social interactions between individuals.
i.e.;
1) Individual response is nested within a group response.
2) The same environmental predictors apply to both hierarchical levels but,
3) Lower level slope/intercept are also affected by high-level response.

Isolating rails model specs from their implementation
I''m currently taking a Rails project management app I built when
learning Rails and adding specs to it. During the course of building
the app the requirement that project should be archiveable was added.
So a project is in one of two states active or archived.
This led to the creation of the following methods:
Project.active_projects
Project.archived_projects

polynomial predict with lme
Does lme prediction work correctly with poly() terms?
In the following simulated example, the predictions
are wildly off.
Or am I doing something daft?
Milk yield for five cows is measured weekly for 45 weeks.
Yield is simulated as cubic function of weekno + random
cow effect (on intercept) + residual error.
I want to recover an estimate of the fixed curve.

Nolinear mixed-effects models (nlme)
Hello,
I am trying to fit a nonlinear model of the form of:

COW to be a random effect.
I have been trying the following code with very littel success:

calculating distance inland from coastline
Hi All,
Does anybody know of any existing functions that will calculate distance
inland from a coastline?
It's possible to test if a lon,lat location is land or sea using
map.where(), but I need to add a buffer to this of say 2km, to allow for
points that are just on the coast, and below the resolution of the
worldHires database.

Comparing formulas
Dear All,
I want to compare formulas resulting from using stepAIC() on glm() objects.
I have 2 different formulas, say F1 and F2, which consist of about 10
factors (Y~A+B+C+...) but one has an interaction term (A:B) while the other
doesn't. But when I perform F1==F2 it comes back as TRUE. Is there a proper
way to compare formulas?
