The following changes were made since the last patchlevel:
2011-05-14:
- Fixed problems with SPSS system files that do not contain an 'info_flt64' record. This problem led to zeroes in the data section of the file being erroneously interpreted as sysmis.
- Fixed 'show' and 'print' methods for 'data.set' objects - they no do fit the width set by options(width=...), without ugly line breaks.
- Changed the default value of the 'compress.storage.modes' option for the subset and bracket methods o 'importer' objects to ...
Sandwich estimators and 'mtable'
Posted on Fri, 13 May 2011 21:46:19 +0100
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. One trick to make use of this extension is to add a class attribute "lm_sandwich" or "glm_sandwich", respectively, to your lm or glm object like in this example:

RZ - a GUI for Data Management with memisc
Posted on Tue, 10 May 2011 12:13:40 +0100
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.
memisc 0.95-31

memisc 0.95-30
Posted on Mon, 12 Apr 2010 21:42:18 +0100
A new patchlevel (0.95-30) of my memisc package is on CRAN now..
The following changes were made since the last patchlevel:
2010-04-12:
- 'toLatex(mtable(
),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'.

- 'mtable' now handles objects of classes "polr" and "simex", thanks to a contribution from Christopher N. Lawrence (Texas A&M International University)
- support for 'mtable' output for "glm" objects with exponentiated coefficients and prelininary support for "lmer" object added, thanks to a ...
