833 : feinerer 22 * R/textdoccol.R: Constructor of textdoccol allows import of CSV
834 :     files. See the questionnaire data/Umfrage.csv for such an example.
835 : feinerer 23 We are now able to import files in Reuters-21578 XML format.
836 : feinerer 22
837 : feinerer 799 * Changed class interfaces in various files. Weighting of the text
838 : feinerer 21 matrix is now possible.

841 :    
842 :     * R/textdoccol.R: One can build term-document matrices if
843 :     nessecary (with buildTDM(...)) and fill the field tdm from a text
844 :     document collection with it.
845 :    
846 :     * R/textmatrix.R: Wrote S4 class for term-document matrices.

854 :    
855 :     * R/textdoccol.R: Set up an S4 class for a collection of text
856 :     documents. A first attempt to read in XML input (like the RCV1
857 :     set) was made.
858 :    
859 :     * R/textdocument.R: Set up an S4 class for text documents. Wrote
860 :     some accessor functions.
861 :    
862 :     * data/newsitem.xml: Added this XML file for testing purposes. It
863 :     contains a single news item from the Reuters Corpus Volume 1

867 :    
868 :     * R/textmatrix.R (textmatrix): Removed the transpose of the original
869 :     textmatrix as k-means clustering provided by R (kmeans) now works on
870 :     this textmatrix. The result is a k-means text clustering with a
871 :     similarity measure based upon word frequences.

874 :    
875 :     * R/textmatrix.R: Adapted the preprocessing code from the R
876 :     package "lsa" written by Fridolin Wild to build a document text matrix.
