manipulating multiply imputed data sets
Hi folks,
I have five imputed data sets and would like to apply the same
recoding routines to each. I could do this sort of thing pretty
easily in Stata using MIM, but I've decided to go cold turkey on other
stats packages as a incentive for learning more about R. Most of the
recoding is for nominal variables, like race, religion, urbanicity,
and the like. So, for example, to recode race

Primer for working with survey data in R
I am taking a behavioral stats graduate class and the instructor is using
SPSS. I'm trying to follow along in R.
Recently in class we started working with scales and survey data, computing
Cronbach's Alpha, reversing values for reverse coded items, etc.
Also, SPSS has some built in functionality for entering the meta-data for
your survey, e.g. the possible values for items, the text of

Primer for working with survey data in R
Dear Kevin,
In addition to the advice you've received, take a look at the survey package. It's not quite what you're asking for, but in fact it's probably more useful, in that it provides correct statistical inference for data collected in complex surveys. The package is described in an article, T. Lumley (2004), Analysis of complex survey samples, Journal of Statistical Software

Direct Method Age-Adjustment to Complex Survey Data
Hi everyone, my apologies in advance if I'm overlooking something simple in
this question. I am trying to use R's survey package to make a direct
method age-adjustment to some complex survey data. I have played with
postStratify, calibrate, rake, and simply multiplying the base weights by
the correct proportions - nothing seems to hit the published numbers on the
nose.

CI from svyquantile in survey package
I am having trouble understanding (i.e. getting) confidence intervals from
the survey package. I am using R version 2.8.1 (2008-12-22) and survey
package (3.11-2) on FC7 linux. To simplify my question I use an example from
that package:

Design of a survey using the "survey" package
I have looked through the new "Complex Surveys" book and the documentation
for the "survey" package and it appears to me that there are no functions in
"survey" that help one to design a sampling scheme. For example, in the book
section 2.8 discusses the design of stratified samples, but there is no
mention of any functions in the "survey" package that

using aggregate with survey-design and survey functions
Hi R users,
I am trying to use the aggregate function with a survey design object and
survey functions, but get the following error. I think I am incorrectly using the
syntax somehow, and it may not be possible to access variables directly by
name in a survey-design object. Am I right? How do I fix this problem? I have
used aggregate with "mean" and "weighted.mean", and

Post stratification weights in survey package in R
Hi all,
I have data collected from a survey administered on a subset of the
population. I also have the population proportions of variables such as
gender, race and housing type. I would like to combine the weights from
each separate cross tab (of gender, race and housing type) such that the
weighted proportions of my survey data matches that of the population.
I have tried the following:

Survey questions
First the R question. I have the results of a rather large survey
(thousands of forms, each with dozens of questions) with some existing
weights and expansion factors. I wish to add additional weighting
factors, based on new information that elements of certain variables
should appear in certain proportions. Where should I look in R to
develop what is essentially an N-dimensional balancing

weighting (survey) data
Hi,
is there a function in R equivalent to the "weight by"-command in SPSS?
I'm working with survey datasets and the data need to be weighted by a
survey/ probability/ design weight (to compensate for different
probabilities to be included in the sample in each country). The
weight variables are included in the datasets.
I did find functions in the Hmisc and survey packages that

Data Mining Survey
Dear R-Helpers,
SAS Institute just mailed out the notice below regarding a survey of
people who do data mining. To help keep the survey from becoming biased
toward commercial software, I thought it would be good to post it here

The inaugural Shorewall survey!
Greetings to all of the Shorewall community!
We''d like to find out a little more about the environments in which
Shorewall runs, and to this end i''ve created a survey. It is mostly
designed to allow Shorewall users to see how their environment compares
with that of the average Shorewall user (if such a thing exists!), but
the results may be used by the Shorewall team to assist

survey: estimating a covariance matrix
Hello
Does anybody happen to know if it is possible to use the survey package to
estimate a covariance matrix from a complex survey?
I have design weights and clusters (no strata), and want to get a covariance
matrix with preferably the effective sample size or else an estimate of the
variance-covariance matrix of the covariance matrix ("asymptotic covariance
matrix"). Is this

ordered logistic regression of survey data with missing variables
Hello:
I am working with a stratified survey dataset with sampling weights
and I want to use multiple imputation to help with missingness.
1. Is there a way to run an ordered logistic regression using both a
multiply imputed dataset (i.e. from mice) and adjust for the survey
characteristics using the weight variable? The Zelig package is able
to do binary logistic regressions for survey

longitudinal survey data
Dear R-Users!
Is there a possibility in R to do analyze longitudinal survey data (repeated
measures in a survey)? I know that for longitudinal data I can use lme() to
incorporate the correlation structure within individual and I know that there is
the package survey for analyzing survey data. How can I combine both? I am
trying to calculate design-based estimates. However, if I use svyglm() from
