840 : feinerer 29 data set.
841 :    
842 : feinerer 799 * Finished documentation and reordered directory structure. Now "R

862 : feinerer 23 We are now able to import files in Reuters-21578 XML format.
863 : feinerer 22
864 : feinerer 799 * Changed class interfaces in various files. Weighting of the text
865 : feinerer 21 matrix is now possible.

868 :    
869 :     * R/textdoccol.R: One can build term-document matrices if
870 :     nessecary (with buildTDM(...)) and fill the field tdm from a text
871 :     document collection with it.
872 :    
873 :     * R/textmatrix.R: Wrote S4 class for term-document matrices.
874 :    
875 : feinerer 19 2005-11-06 Ingo Feinerer <h0125130@wu-wien.ac.at>
876 :

881 :    
882 :     * R/textdoccol.R: Set up an S4 class for a collection of text
883 :     documents. A first attempt to read in XML input (like the RCV1
884 :     set) was made.
885 :    
886 :     * R/textdocument.R: Set up an S4 class for text documents. Wrote
887 :     some accessor functions.
888 :    
889 :     * data/newsitem.xml: Added this XML file for testing purposes. It
890 :     contains a single news item from the Reuters Corpus Volume 1

894 :    
895 :     * R/textmatrix.R (textmatrix): Removed the transpose of the original
896 :     textmatrix as k-means clustering provided by R (kmeans) now works on
897 :     this textmatrix. The result is a k-means text clustering with a
898 :     similarity measure based upon word frequences.
