Repeated measures logistic regression
Dear all,
I'm struggling to find the best (set of?) function(s) to do repeated
measures logistic regression on some data from a psychology experiment.
An artificial version of the data I've got is as follows. Firstly,
each participant filled in a questionnaire, the result of which is a
score.

piecewise linear regression
We sent questionnaires to lots of folks. The questionnaires
differed in word count (wc). For each questionnaire, I know wc
and whether the questionnaire was returned or not (status). It
looks like there is a fixed rate of return when wc is below a
break point, and the rate of return falls off linearly after
that.
I want to do a piecewise linear regression with two pieces

using survey weights for correlations
Dear list,
I have a data file which includes, alongside various variables representing questionnaire scores, a variable for survey weights computed as the number of observations in the sample drawn from that group divided by the number of observations in the population in the group. I need to calculate a covariance matrix of the questionnaire scores for use in sem. How do I apply the weights?

How should I organize data to compare differences in matched pairs?
I'm just learning how to use R right now, so I'm not sure what the most
efficient way to organize these data is.
I had subjects perform the same task twice with slight changes between the
rounds. I want to analyze differences between the rounds. All of the
subjects also answered a questionnaire.
Putting all of one subject's information on one row seems sloppy.

merging dataframes with an unequal number of variables

I have the kind of problem that one should never have because one must
always plan well and communicate with your team. But now I haven't so here
is my problem.
I have data coming in on a daily basis from surveys in 10 towns. The
questionnaire has 62 variables but some of the regions have used older

Is there a better way for inputing data manually?
Dear All,
I have worked with R for some time. It's a great tool for data analysis. But it's too hard to inputing raw data manually with R (I don't mean importing data. R is good at importing data). Maybe it's not a focused topic in this list, but I don't know other place where I can ask the question. How do you do when inputing data from a paper material, such as

Automatically adjust text size in plot
Hi all,
I'm writing a function that will automatically generate a report based
on answers to a questionnaire. The exact questions and answers to the
questionnaire can vary. One of the question types is in a "matrix"
format, where the agreement to several statements can be indicated on
a scale.
I'm planning to plot this on a multilevel barplot, and only labeling

Ordinal response model
I have been asked to analyse some questionnaire data- which is not data I'm
that used to dealing with. I'm hoping that I can make use of the nabble
expertise (again).
The questionnaire has a section which contains a particular issue and then
questions which are related to this issue (and potentially to each other):
1) importance of the issue (7 ordinal categories from -3 to +3)

Controller and Model Responsibilities
Hi everyone,
I am wondering what code has to go into the controller and what into
the model. Generally I would think that all operations that keep the
model in a proper state should be done within the model, and the
controller should only provide the actions necessary to carry out the
application''s use cases. Am I right so far?
My situation is the following. Whenever an admin performs

Questionnaire Analysis virtually without continuous Variables

Clinical Trial data sets in public domain?
Is anybody using R to do analysis of clinical trial datasets that have been

[ For example, "Adverse Events" and "Patient Info" are two datasets with a

Package or packages for randomization in a clinical trial
Can anyone recommend a package that can be used to randomize subjects? I am looking for a generalized package, or several packages that can accomplish
unrestricted randomization (i.e. simple random assignment)
restricted randomization including stratified randomization, blocked randomization, and adaptive randomization.
Thanks,
