destroy vs delete
what is the difference between destroy and delete in AR
I am not sure what they mean by
"Destroys the record with the given id by instantiating the object and
calling destroy<http://api.rubyonrails.com/classes/ActiveRecord/Base.html#M000866>(all
the callbacks are the triggered). If an array of ids is provided, all
of them are destroyed."

S4 - inheritance changed by order of setClassUnion and setAs()
Andreas,
As far as I can tell (/conjecture), this is because the list of classes a
particular class inherits from directly is appended to as needed, and so
the order that a class extends others isd refined by the order that those
connections are defined.
We can see this with two setClassUnion calls, rather than required setAs:
> setClass("grandma", slots = c(a =

best practice deployment
what is the best method to deploy from a development machine to production
when you need slightly different files for each mode
do you use TWO files such as db.yml.dev and db.yml.prod
and use capistrano to deploy one or the other to database.yml
or is it better to have one file
and use conditions in your file such as
<% if ENV[''RAILS_ENV''] = "production" %>

Incorrect shell quotation in scp
Hi,
as the current debian maintainer of the openssh package is a bit busy,
I'm helping him with fixing a part of the bugs in openssh that debian
users found will forward some of the reports to you. This is the first
one and a fix or a comment why this should not be fixed would be
appropriated. Thanks

CRAN task view: Multivariate
Hello,
I've assembled a Multivariate ctv (with a lot of help from Achim Zeleis,
who has now posted the view on CRAN).
I'd be grateful for comments regarding missing packages / functions.
Opinions on the organisation of the view would also be appreciated, as
well as having any errors pointed out. I've adopted a rather broad and
vague definition of "multivariate", which may

has and belongs to many different?
Is there such a thing? I am thinking of an application that has
something like this:
1. person has many things - there is a ''persons'' table
2. the things he has are stored in a table that is something like this
person_id, thing_table_name, thing_id
For example, it may map to
person1, books, 23 #Person 1 owns book 23
person1, books, 25 #Person 1 owns book 25

Recoding a multiple response question into a series of 1, 0 variables
Hello R folks.
1) The question that generated the data, which I call Qx:
Which of the following 5 items have you performed in the past month? (multipe response)
2) How the data is coded in my current dataframe:
The first item that a person selected is coded under a field called Qxfirst; the second selected under Qxsecond, etc. For the first Person, the NAs mean that that person only selected

Local Moran's I / Getis and Ord and Rousseauw Cluster Algorithms
Sorry for the repetition, unless I've got bad deja vu this questions been
asked before but I couldn't turn up an answer on CRAN. Is there already
any code in existence for local dependence measures such as Moran's I or
Getis and Ord G?
Also, S-Plus has a number of interstingly named Cluster Algorithms based on
some previous stand-alone fortran algorithms (agnes, daisy etc.) which

Hi all.
I am currently thinking about how to do the following:
I have the following models.
Team
Person
Team has various positions (manager, programmer etc.) I would like each
one of those positions to reference one or more Person records. A single
Person record could be on 6 different teams at the same time in
different roles. the same person could even be on the same team multiple
times

pairs: altering pch options on upper and lower panel of pairwise scatter plots
Hello,
I can't figure out how to use the upper.panel and lower.panel options in
pairs to alter the label options for either panel independently of the
other.
I would like to be able to show the pairwise scatter plots for the data
as they are (a vanilla pairs plot?) but separately to be able to label
the points according to a factor level. It is easy enough to do this
independently, but I

I'm having the same issue! The difference in my case is Asterisk server has
a public IPv4 and the browser is behind a single NAT.
I'm forwarding my configuration below (which I posted previously on

How can we debug ICE negotiation?
