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

has_many :through with multiple paths
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

S4 - inheritance changed by order of setClassUnion and setAs()
Dear colleagues,
there is a behaviour with S4 (virtual) classes that I find very hard to understand: Depending on the position
of setAs(), the tree of inheritance changes.
This is my baseline example that defines the classes "grandma", "mother", "daughter" and a virtual
class "mr_x". For a new instance if "daughter", "mr_x" is betweeen

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

I created a self-referential many-to-many relationship (as described
in the book Rails recipe #18), where I have a model that has
many-to-many relationships with itself. In this case, it''s person who
can become friends. The join table looks like this:

Attempting to recode elements contained in a list
Hello R-Masters,
I have a list 's' with three elements, as shown below. I want to recode a.a, a.a2, and a.a3 to NA if the value in a.a is less than 3.
I reivewed my Modern Applied Statistic Book, the online help and did some searching of R-help on the internet. I explored unlist and as.list.data.frame in an attempt to isolate the third element of the list s, but this was not helpful.

Seeking help for outomating regression (over columns) and storing selected output
Hello,
I have spent considerable time trying to figure out that which I am about to describe. This included searching Help, consulting my various R books, and trail and (always) error. I have been assuming I would need to use a loop (looping over columns) but perhaps and apply function would do the trick. I have unsuccessfully tried both.
A scaled down version of my situation is as follows:

Would like to apply a weight variable to the summary function in Hmisc
Hello,
In the Hmisc package, functions describe and summarize can explicitly take a
weight variable.
My question is can a weight variable be applied when using 'summary'?
For example, using...summary(var1 ~ var2) I would like to weight the data
by var 3 (same length).
Is this possible?
Thanks a lot.
