143 :     * R/textdocument.R: Set up an S4 class for text documents. Wrote
144 :     some accessor functions.
145 :    
146 :     * data/newsitem.xml: Added this XML file for testing purposes. It

152 :     * R/textmatrix.R (textmatrix): Removed the transpose of the original
153 :     textmatrix as k-means clustering provided by R (kmeans) now works on
