816 : feinerer 799 * Changed class interfaces in various files. Weighting of the text
817 : feinerer 21 matrix is now possible.

820 :    
821 :     * R/textdoccol.R: One can build term-document matrices if
822 :     nessecary (with buildTDM(...)) and fill the field tdm from a text
823 :     document collection with it.
824 :    
825 :     * R/textmatrix.R: Wrote S4 class for term-document matrices.

828 :    
829 :     * R/textdoccol.R: We now can read in a whole XML file with several
830 :     news items.

832 : feinerer 17 2005-11-05 Ingo Feinerer <h0125130@wu-wien.ac.at>
833 :    
834 :     * R/textdoccol.R: Set up an S4 class for a collection of text
835 :     documents. A first attempt to read in XML input (like the RCV1
836 :     set) was made.
837 :    
838 :     * R/textdocument.R: Set up an S4 class for text documents. Wrote
839 :     some accessor functions.
840 :    
841 :     * data/newsitem.xml: Added this XML file for testing purposes. It
842 :     contains a single news item from the Reuters Corpus Volume 1
843 :     (RCV1) XML set.

846 :    
847 :     * R/textmatrix.R (textmatrix): Removed the transpose of the original
848 :     textmatrix as k-means clustering provided by R (kmeans) now works on
849 :     this textmatrix. The result is a k-means text clustering with a
850 :     similarity measure based upon word frequences.

853 :    
854 :     * R/textmatrix.R: Adapted the preprocessing code from the R
855 :     package "lsa" written by Fridolin Wild to build a document text matrix.
