818 :     * R/textdoccol.R: We now can read in a whole XML file with several
819 :     news items.

822 :    
823 :     * R/textdoccol.R: Set up an S4 class for a collection of text
824 :     documents. A first attempt to read in XML input (like the RCV1
825 :     set) was made.
826 :    
827 :     * R/textdocument.R: Set up an S4 class for text documents. Wrote
828 :     some accessor functions.
829 :    
830 :     * data/newsitem.xml: Added this XML file for testing purposes. It
831 :     contains a single news item from the Reuters Corpus Volume 1

835 :    
836 :     * R/textmatrix.R (textmatrix): Removed the transpose of the original
837 :     textmatrix as k-means clustering provided by R (kmeans) now works on
838 :     this textmatrix. The result is a k-means text clustering with a
839 :     similarity measure based upon word frequences.

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