The R package *memisc*, which is available at CRAN, provides tools for the management of survey data, graphics, statistics and simulation. The version published on CRAN is available here.

Although it is handy to have a lot of functionality collected into one package, such a package also creates its own challenges for maintenance. For this reason I am splitting up the package in several smaller ones that will soon appear on this website as well as (hopefully) on CRAN. This webpage will contain news related to *memisc* and the packages to supersede it.

One of the facilities that the package provides is the for the creation of (nearly) publication-ready tables of estimates. One example can be found on a separate page.

In addition to formatted output of estimates *memisc* also assist in conducting *simulation experiments*. An example is given on a page on the function `Simulate`

.

Another utility function contained in the *memisc* package is `Termplot`

which is an enhanced version of the standard *R* function `termplot`

. `Termplot`

allows to 'compare' the fit of different models. An example can be found on a seperate page.

More examples for the use of the package are given in the package vignette.

- Changed the default value of the 'compress.storage.modes' option for the subset and bracket methods o 'importer' objects to ...

#### Package "memisc": Sandwich estimators and 'mtable'

Posted on Fri, 13 May 2011 21:46:19 +0200

Recently I was asked whether it was possible to use with 'mtable' sandwich estimators of variance for *lm* and *glm* models, as they are provided by the *R* packages 'sandwich' and 'lmtest'.

An *R* script that provides this extension can now be downloaded from here.

#### Extensions for 'mtable' in R package "memisc"

Posted on Tue, 10 May 2011 12:28:38 +0200

#### RZ - a GUI for Data Management with memisc

Posted on Tue, 10 May 2011 12:13:40 +0200

Masahiro Hayashi has written a graphical user interface for the data management facilities that my package 'memisc' provides.

This package can be found here. It looks promising but seems to lack documentation. I am going to check it out more intensively in the next weeks.

For a start, here is a screenshot.

Posted on Mon, 12 Apr 2010 21:42:18 +0200

),useDcolumn=FALSE)' should now produce useable LaTeX output (dollars are added to the table entries).

2010-04-09:

- 'By' works now with 'genTable' and 'aggregate.formula'. It gains a 'data.frame' method, which better cooperates with calls to 'lm'-like functions. Their results get a 'data' component containing the subset of the data frame that was given as 'data' argument to the call of 'By'.
