A new release 0.99.17.1 of my package memisc has been published on `CRAN`_.
The new release has the following improvements:

  - ``mtable()`` results now include a legend for significance symbols.
  - A ``codeplan()`` function creates a data frame that describes the
    structure of an ``"importer"`` or ``"data.set"`` object.  Such
    "codeplans" can be used to copy the "item structure" or code plan from
    one object to another.
  - The ``subset()`` method for ``"importer"`` objects now accepts the names of
    variables to be selected also as a character vector.
  - Dollar and double-bracket operators for ``"importer"`` objects are
    available to facilitate creating codebooks for individual variables.
  - Summary statistics for models in calls to ``mtable()`` can be selected
    via options or list arguments.
  - ``toLatex()`` method for ``mtable()`` results warns about unescaped TeX
    specials
  - A ``dublicated_labels()`` function shows and describes duplicated value
    labels. The importer methods for SPSS (``spss.system.file()`` and
    ``spss.portable.file()``) files use this to warn about duplicated
    labels.
  - Dates are properly imported from SPSS files and their representation in
    codebooks is improved.
  - Operators ``%#%``, ``%##%``, and ``%@%`` make it easier to manipulate
    annotations and other attributes of objects.
