polmineR 0.7.10

NEW FEATURES

  • The package now offers a simplified and seamless workflow for dictionary-based sentiment analysis: The weigh()-method has been implemented for the classes count and count_bundle. Via inheritance, it will also be available for the partition- and partition_bundle-classes. Then, a new summary()-method for partition-class objects is introduced. If the object has been weighed, the list that is returned will include a report on weights. There is an example that explains the workflow.
  • The partition_bundle-method for context-objects has been reworked entirely (and is working again); a new partition-method for context-objects has been introduced. Buth steps are intended for workflows for dictionary-based sentiment analysis.
  • The highlight()-method is now implemented for class kwic. You can highlight words in the neighborhood of a node that are part of a dictionaty.
  • A new knit_print()-method for textstat- and kwic-objects offers a seamless inclusion of analyses in Rmarkdown documents.
  • A coerce()-method to turn a kwic-object into a htmlwidget has been singled out from the show()-method for kwic-objects. Now it is possible to generate a htmlwidget from a kwic object, and to include the widget into a Rmarkdown document.
  • A new coerce()-method to turn textstat-objects into an htmlwidget (DataTable), very useful for Rmarkdown documents such as slides.
  • A new argument height for the html()-method will allow to define a scroll box. Useful to embed a fulltext output to a Rmarkdown document.

MINOR IMPROVEMENTS

  • The partition_bundle-class, rather than inheriting from bundle-class directly, will now inherit from the count_bundle-class
  • The use()-function is limited now to activating the corpus in data packages. Having introduced the session registry, switching registry directories is not needed any more.
  • The as.regions()-function has been turned into a as.regions()-method to have a more generic tool.
  • Some refactoring of the context-method, so that full use of data.table speeds up things.
  • The highlight()-method allows definitions of terms to be highlighted to be passed in via three dots (...); no explicit list necessary.
  • A new as.character()-method for kwic-class objects is introduced.

BUG FIXES

  • The size_coi-slot (coi for corpus of interest) of the context-object included the node; the node (i.e. matches for queries) is excluded now from the count of size_coi.
  • When calling use(), the registry directory is reset for CQP, so that the corpora in the package that have been activated can be used with CQP syntax.
  • The script configure.win has been removed so that installation works on Windows without an installation of Rtools.
  • Bug removed from s_attributes()-method for partition-objects: "fast track" was activated without preconditions.
  • Bug removed that would swallow metadata/s-attributes to be displayed in kwic-output after highlighting.
  • As a matter of consistency, the argument meta has been renamed to s_attributes for the kwic()-method for context-objects, and for the enrich()-method for kwic-objects.
  • To avoid confusion (with argument s_attributes), the argument s_attribute to check for integrity within a struc has been renamed into boundary.

DOCUMENTATION FIXES

  • Documentation for kwic-objects has been reworked thoroughly.
