2 :    
3 : feinerer 51 * data/: Examples compiled for new features
4 :    
5 :     * R/: Changes due to new structure.
6 :    
7 : feinerer 50 * NAMESPACE: Corrected namespace to reflect new structure.
8 :    
9 :     * R/termdocmatrix.R: Adapted for new naming scheme.
10 :    
11 : feinerer 49 2006-08-06 Ingo Feinerer <h0125130@wu-wien.ac.at>
12 :    
13 :     * R/textdoccol.R: Adapted code for new class structure. Wrote
14 :     several transform and filter functions operating on text document
15 :     collections (alias text document databases).
16 :

100 :    
101 :     * R/textdoccol.R: One can build term-document matrices if

103 :     document collection with it.
104 :    
105 :     * R/textmatrix.R: Wrote S4 class for term-document matrices.
106 :

113 :    
114 :     * R/textdoccol.R: Set up an S4 class for a collection of text
115 :     documents. A first attempt to read in XML input (like the RCV1
116 :     set) was made.
117 :    
118 :     * R/textdocument.R: Set up an S4 class for text documents. Wrote
119 :     some accessor functions.
120 :    
121 :     * data/newsitem.xml: Added this XML file for testing purposes. It
122 :     contains a single news item from the Reuters Corpus Volume 1
123 :     (RCV1) XML set.
124 :    
125 : feinerer 16 2005-10-07 Ingo Feinerer <h0125130@wu-wien.ac.at>
126 :    
127 :     * R/textmatrix.R (textmatrix): Removed the transpose of the original
128 :     textmatrix as k-means clustering provided by R (kmeans) now works on
129 :     this textmatrix. The result is a k-means text clustering with a
130 :     similarity measure based upon word frequences.
131 :    
132 :     2005-10-05 Ingo Feinerer <h0125130@wu-wien.ac.at>
133 :
