150 :     set) was made.
151 :    
152 :     * R/textdocument.R: Set up an S4 class for text documents. Wrote
153 :     some accessor functions.
154 :    
155 :     * data/newsitem.xml: Added this XML file for testing purposes. It
156 :     contains a single news item from the Reuters Corpus Volume 1

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

164 :     similarity measure based upon word frequences.
