135 :     * R/textdoccol.R: Set up an S4 class for a collection of text

137 :     set) was made.
138 :    
139 :     * R/textdocument.R: Set up an S4 class for text documents. Wrote
140 :     some accessor functions.
141 :    
142 :     * data/newsitem.xml: Added this XML file for testing purposes. It
143 :     contains a single news item from the Reuters Corpus Volume 1
144 :     (RCV1) XML set.

147 :    
148 :     * R/textmatrix.R (textmatrix): Removed the transpose of the original
149 :     textmatrix as k-means clustering provided by R (kmeans) now works on
150 :     this textmatrix. The result is a k-means text clustering with a
151 :     similarity measure based upon word frequences.
152 :
