How to use 'switch' with strings containing spaces?
Hi,
Does anyone know if the alternatives in the 'switch' function can be specified as strings containing spaces? Neither of the two approaches below works.
switch(expr, "Choice 1"="My first choice", "Choice 2"="My 2nd choice", "Choice 3"="My 3rd choice")
x <- c("Choice 1", "Choice 2", "Choice 3")
switch(expr, x[1]="My first choice", x[2]="My 2nd choice", x[3]=&quo...

Association collections problems
Hi all!
I find association collections to be quite hard to understand and use.
I have a Leg class that has_many :choices, and a Choice class that
belongs_to :leg. In a controller I want to update both a Leg and its
Choices. If I do it like this:
@leg.choices.update params[:choice].keys, params[:choice].values
It updates the database directly (or more specifically only updates
records that validates). So if I wa...

Data transformation & cleaning
Hi,
I have a few methodological and implementation questions for ya'll. Thank
you in advance for your help. I have a dataset that reflects people's
preference choices. I want to see if there's any kind of clustering effect
among certain preference choices (e.g. do people who pick choice A also pick
choice D).
I have a data set that has one record per user ID, per preference choice.
It's a "long" form of a data set that looks like this:

panel.arrows problem in custom panel function
...e("xyplot.procrustes.R")
xyplot(vare.proc, y ~ x | groups, data = as.data.frame(groups), kind = 1)
The resulting plot has too many arrows on each panel - some points have
multiple arrows emanating from they. panel.procrustes() is defined as:
`panel.procrustes` <- function(x, y, kind, choices, rotation, X,
ar.col, length = 0.05, ...) {
tp <- trellis.par.get()
if(missing(ar.col))

choice-based conjoint
Hello everyone,
I am new to this list and the R-Project, so I hope my question is not
trivial or has been answered before. I searched the FAQs and the mailing
list archives and I could not find anything about Conjoint Analysis. I am
especially interested in Choice-based Conjoint, resp. discrete choice
models.
Is there a function / module that handles this issue? Or can the multinomial
logit model be used? I would doubt the latter, for in a Choice-based
Conjoint analysis the choice has to be conditioned to the alternatives in
the choice set which are not eq...

MNP - discrete choice experiment
Hello,
I need a little initial help with the MNP package.
I am trying to analyze a discrete choice experiment with the following
settings:
- choice sets consist of 3 alternatives
- choice alternatives are constructed by e.g. two attributes, say brand and
price.
- brand has three levels and price has four levels
- every respondent has to answer 4 different choice sets (drawn randomly or

I would like to fit different kinds of model (logit ,nested logit,

with varying choice set.
But for estimation of a logit model, I have only found function *...

I'd like to announce the availability of a mailing list for a

design and analysis of Discrete Choice (aka Stated Choice, Stated
Preference or Choice-Based Conjoint) experiments.
