Crosstabbing multiple response data
Using R version 2.4.1 (2006-12-18) on Windows, I have a dataset which resembles this:
id att1 att2 att3
1 1 1 0
2 1 0 0
3 0 1 1
4 1 1 1
ratings <- data.frame(id = c(1,2,3,4), att1 = c(1,1,0,1), att2 = c(1,0,0,1), att3 = c(0,1,1,1))
I would like to get a cross tab of counts of co-ocurrence, which might resemble this:

how to add a child to a child in XML
Big thanks. newXMLNode works great. Wonder why it is not included in the documentation.
There is newXMLDoc and newXMLNamespace, but no mention of newXMLNode.

how to add a child to a child in XML
Hi,
XML doesn't use the `$` to access child nodes. Instead use either `[name]` to get a list of children of that name or `[[name]]` to get the just the first child of that name encountered in the genealogy. Thus for your example...
> root$child1
NULL
> root[['child1']]
<child1 name1="A" name2="B" name3="C"/>

how to add a child to a child in XML
Hi,
It's a reasonable question. The answer is that it actually is included, but there are many instances across packages where multiple functions are documented on a single help page. The following brings up such a page... (for XML_3.98-1.9)
> library(XML)
> ?newXMLNode
You can see the same on line...

how to add a child to a child in XML
Just to clarify and hopefully catch the attention of the maintainer:
The newXMLNode function is not mentioned in:
https://cran.r-project.org/web/packages/XML/XML.pdf
which supposedly describes all functions in the package.

Cant test 404 pages in webrick
I tried running webrick in production mode with -e production option. I
changed development database name so as to make sure webrick was running
in production mode.
Now I wanted to test my new 404.html page so I typed an invalid URL, I
still get some routing error instead of my 404.html page.
Why is this happening with webrick in production. I haven''t even changed
any of the environment

Modify objects in function
Dear R community,
I do know, that an R function is constructing a copy of any object passed as argument into a function. I program on a larger S4 project for a package, and I arrived at a point where I have to think a little harder on implementation style (especially to spare users complex object handling).
I have a function foo(), taking as input arguments two S4 objects of different class

[LLVMdev] [RFC] Storing default function attributes on the module
Hi Duncan,
Been thinking about this a bit and a few comments/questions. I may have
misunderstood some things in your mail though so please feel free to
explain at me :)

before_create is after_validatation :on => :create , when it should be before_validation :on => :create
In ActiveRecord''s callbacks, methods within a before_create callback
are called after the validation, but before the model is created.
This was an intentional design decision, but I think it was the wrong
one. What do you think?
When I think of before_create, I think of before_validation :foo, :on
=> :create, but, by default, before_create is synonymous with
after_validation :foo,

self in before_create
Hi, I am having a small problem concernig how to access local variables in
before_create. I am not sure how to really form this question but here goes:
I am wondering why this works
def before_create
self.last_logged_in = Time.now
self.created = Time.now
end
but this doesn''t
def before_create
@last_logged_in = Time.now
@created = Time.now
end
The latter fails
