111 :    
112 :     * R/textdoccol.R: One can build term-document matrices if

124 :    
125 :     * R/textdoccol.R: Set up an S4 class for a collection of text

127 :     set) was made.
128 :    
129 :     * R/textdocument.R: Set up an S4 class for text documents. Wrote
130 :     some accessor functions.
131 :    
132 :     * data/newsitem.xml: Added this XML file for testing purposes. It
133 :     contains a single news item from the Reuters Corpus Volume 1
134 :     (RCV1) XML set.
135 :    
136 : feinerer 16 2005-10-07 Ingo Feinerer <h0125130@wu-wien.ac.at>
137 :    
138 :     * R/textmatrix.R (textmatrix): Removed the transpose of the original
139 :     textmatrix as k-means clustering provided by R (kmeans) now works on
140 :     this textmatrix. The result is a k-means text clustering with a
141 :     similarity measure based upon word frequences.
142 :    
143 :     2005-10-05 Ingo Feinerer <h0125130@wu-wien.ac.at>
144 :
