New memisc release 0.99.17.1 with new capabilities for data preparation¶

23 March 2019

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.
