817 :     files. See the questionnaire data/Umfrage.csv for such an example.
818 : feinerer 23 We are now able to import files in Reuters-21578 XML format.
819 : feinerer 22
820 : feinerer 799 * Changed class interfaces in various files. Weighting of the text
821 : feinerer 21 matrix is now possible.

825 :     * R/textdoccol.R: One can build term-document matrices if
826 :     nessecary (with buildTDM(...)) and fill the field tdm from a text
827 :     document collection with it.
828 :    
829 :     * R/textmatrix.R: Wrote S4 class for term-document matrices.

832 :    
833 :     * R/textdoccol.R: We now can read in a whole XML file with several
834 :     news items.

836 : feinerer 17 2005-11-05 Ingo Feinerer <h0125130@wu-wien.ac.at>
837 :    
838 :     * R/textdoccol.R: Set up an S4 class for a collection of text
839 :     documents. A first attempt to read in XML input (like the RCV1
840 :     set) was made.
841 :    
842 :     * R/textdocument.R: Set up an S4 class for text documents. Wrote
843 :     some accessor functions.
844 :    
845 :     * data/newsitem.xml: Added this XML file for testing purposes. It
846 :     contains a single news item from the Reuters Corpus Volume 1
847 :     (RCV1) XML set.

850 :    
851 :     * R/textmatrix.R (textmatrix): Removed the transpose of the original
852 :     textmatrix as k-means clustering provided by R (kmeans) now works on
853 :     this textmatrix. The result is a k-means text clustering with a
854 :     similarity measure based upon word frequences.

857 :    
858 :     * R/textmatrix.R: Adapted the preprocessing code from the R
859 :     package "lsa" written by Fridolin Wild to build a document text matrix.
