836 : feinerer 29 data set.
837 :    
838 : feinerer 799 * Finished documentation and reordered directory structure. Now "R

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

864 :    
865 :     * R/textdoccol.R: One can build term-document matrices if
866 :     nessecary (with buildTDM(...)) and fill the field tdm from a text
867 :     document collection with it.
868 :    
869 :     * R/textmatrix.R: Wrote S4 class for term-document matrices.
870 :

877 :    
878 :     * R/textdoccol.R: Set up an S4 class for a collection of text
879 :     documents. A first attempt to read in XML input (like the RCV1
880 :     set) was made.
881 :    
882 :     * R/textdocument.R: Set up an S4 class for text documents. Wrote
883 :     some accessor functions.
884 :    
885 :     * data/newsitem.xml: Added this XML file for testing purposes. It
886 :     contains a single news item from the Reuters Corpus Volume 1

890 :    
891 :     * R/textmatrix.R (textmatrix): Removed the transpose of the original
892 :     textmatrix as k-means clustering provided by R (kmeans) now works on
893 :     this textmatrix. The result is a k-means text clustering with a
894 :     similarity measure based upon word frequences.
