2 :    
3 :     * NAMESPACE: Corrected namespace to reflect new structure.
4 :    
5 :     * R/termdocmatrix.R: Adapted for new naming scheme.
6 :    
7 : feinerer 49 2006-08-06 Ingo Feinerer <h0125130@wu-wien.ac.at>
8 :    
9 :     * R/textdoccol.R: Adapted code for new class structure. Wrote
10 :     several transform and filter functions operating on text document
11 :     collections (alias text document databases).
12 :    
13 :     * R/aobjects.R: Adapted class structure with inheritance,
14 :     repositories and additional meta data. Loading files on demand is

19 :     * R/: Some cosmetic cleanups.
20 :    
21 :     * inst/: Removed vignette on clustering. That and much more is now

112 :     set) was made.
113 :    
114 :     * R/textdocument.R: Set up an S4 class for text documents. Wrote
115 :     some accessor functions.
116 :    
117 :     * data/newsitem.xml: Added this XML file for testing purposes. It
118 :     contains a single news item from the Reuters Corpus Volume 1
119 :     (RCV1) XML set.
120 :    
121 : feinerer 16 2005-10-07 Ingo Feinerer <h0125130@wu-wien.ac.at>
122 :    
123 :     * R/textmatrix.R (textmatrix): Removed the transpose of the original
124 :     textmatrix as k-means clustering provided by R (kmeans) now works on
125 :     this textmatrix. The result is a k-means text clustering with a
126 :     similarity measure based upon word frequences.
127 :    
128 :     2005-10-05 Ingo Feinerer <h0125130@wu-wien.ac.at>
