88 :     set) was made.
89 :    
90 :     * R/textdocument.R: Set up an S4 class for text documents. Wrote
91 :     some accessor functions.
92 :    
93 :     * data/newsitem.xml: Added this XML file for testing purposes. It

98 :    
99 :     * R/textmatrix.R (textmatrix): Removed the transpose of the original
100 :     textmatrix as k-means clustering provided by R (kmeans) now works on
