129 :    
130 :     * R/textdoccol.R: Set up an S4 class for a collection of text

132 :     set) was made.
133 :    
134 :     * R/textdocument.R: Set up an S4 class for text documents. Wrote
135 :     some accessor functions.
136 :    
137 :     * data/newsitem.xml: Added this XML file for testing purposes. It
138 :     contains a single news item from the Reuters Corpus Volume 1

141 : feinerer 16 2005-10-07 Ingo Feinerer <h0125130@wu-wien.ac.at>
142 :    
143 :     * R/textmatrix.R (textmatrix): Removed the transpose of the original
144 :     textmatrix as k-means clustering provided by R (kmeans) now works on
145 :     this textmatrix. The result is a k-means text clustering with a
146 :     similarity measure based upon word frequences.
147 :    
148 :     2005-10-05 Ingo Feinerer <h0125130@wu-wien.ac.at>
