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

826 :    
827 :     * R/textdoccol.R: We now can read in a whole XML file with several
828 :     news items.

831 :    
832 :     * R/textdoccol.R: Set up an S4 class for a collection of text
833 :     documents. A first attempt to read in XML input (like the RCV1
834 :     set) was made.
835 :    
836 :     * R/textdocument.R: Set up an S4 class for text documents. Wrote
837 :     some accessor functions.
838 :    
839 :     * data/newsitem.xml: Added this XML file for testing purposes. It
840 :     contains a single news item from the Reuters Corpus Volume 1
841 :     (RCV1) XML set.

844 :    
845 :     * R/textmatrix.R (textmatrix): Removed the transpose of the original
846 :     textmatrix as k-means clustering provided by R (kmeans) now works on
847 :     this textmatrix. The result is a k-means text clustering with a
848 :     similarity measure based upon word frequences.

851 :    
852 :     * R/textmatrix.R: Adapted the preprocessing code from the R
853 :     package "lsa" written by Fridolin Wild to build a document text matrix.
