how to combine imputed data-sets from mice for classfication
Dear R users
I want to combine multiply imputed data-sets generated from mice to do
classfication.
However, I have various questions regarding the use of mice library.
For example suppose I want to predict the class in this data.frame:
data(nhanes)
mydf=nhanes
mydf$class="pos"
mydf$class[sample(1:nrow(mydf), size=0.5*nrow(mydf))]="neg"
mydf$class=factor(mydf$class)

How to pass a model formula as argument to with.mids
Hello
I would like to pass a model formula as an argument to the with.mids
function from the mice package. The with.mids functon fits models to
multiply imputed data sets.
Here's a simple example
library(mice)
#Create multiple imputations on the nhanes data contained in the mice
package.
imp <- mice(nahnes)
#Fitting a linear model with each imputed data set the regular way works

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.
I am trying to

Suppressing Scientific Notation
R gurus,
Every so often(*) someone asks how to suppress scientific notation in
printing, so I thought I'd give it a shot, but I need some help.
The formatting decision is made(**) on line 286 of src/main/format.c :
if (mF <= *m) { /* IFF it needs less space : "F" (Fixpoint) format */
where mF is the number of characters for "normal" printing and *m is the number

bug with OutDec option and deferred_string altrep object
While implementing R's new 'altrep' functionality in the TERR engine,
I discovered a bug in R's 'deferred_string' altrep object: it is not
using the correct value of the 'OutDec' option when it expands a
deferred_string. See the following example:

Multiple Hexbinplots in 2 columns with a Single Categorical Variable

I have a fairly large database (N=13,000) and a single main categorical

mice library / survival analysis
Hello folks,
I am a relatively new user of R and created multiply imputed data sets
with the 'mice' library. This library provides two functions for
complete-data analysis on multiply imputed data set objects (lm.mids and
glm.mids). I am trying to estimate a series of Cox PH regression models
and cannot figure out the best way to do this. Is it possible with the
mitools library?

Calculating mean from wit mice (multiple imputation)
Hi all,
How can I calculate the mean from several imputed data sets with the package
mice?
I know you can estimate regression parameters with, for example, lm and
subsequently pool those parameters to get a point estimate using functions
included in mice. But if I want to calculate the mean value of a variable
over my multiple imputed data sets with
fit <- with(data=imp, expr=mean(y)) and

Multiple Imputation in mice/norm
I'm trying to use either mice or norm to perform multiple imputation to fill
in some missing values in my data. The data has some missing values because
of a chemical detection limit (so they are left censored). I'd like to use
MI because I have several variables that are highly correlated. In SAS's
proc MI, there is an option with which you can limit the imputed values that
