2 :    
3 :     * R/textdoccol.R: One can build term-document matrices if
4 :     nessecary (with buildTDM(...)) and fill the field tdm from a text
5 :     document collection with it.
6 :    
7 :     * R/textmatrix.R: Wrote S4 class for term-document matrices.
8 :    
9 : feinerer 19 2005-11-06 Ingo Feinerer <h0125130@wu-wien.ac.at>
10 :    
11 :     * R/textdoccol.R: We now can read in a whole XML file with several
12 :     news items.
13 :    
14 : feinerer 17 2005-11-05 Ingo Feinerer <h0125130@wu-wien.ac.at>
15 :    
16 :     * R/textdoccol.R: Set up an S4 class for a collection of text
17 :     documents. A first attempt to read in XML input (like the RCV1
18 :     set) was made.
19 :    
20 :     * R/textdocument.R: Set up an S4 class for text documents. Wrote
21 :     some accessor functions.
22 :    
23 :     * data/newsitem.xml: Added this XML file for testing purposes. It
24 :     contains a single news item from the Reuters Corpus Volume 1

28 :    
29 :     * R/textmatrix.R (textmatrix): Removed the transpose of the original
30 :     textmatrix as k-means clustering provided by R (kmeans) now works on
31 :     this textmatrix. The result is a k-means text clustering with a
32 :     similarity measure based upon word frequences.
33 :    
34 :     2005-10-05 Ingo Feinerer <h0125130@wu-wien.ac.at>
35 :    
36 :     * R/textmatrix.R: Adapted the preprocessing code from the R
37 :     package "lsa" written by Fridolin Wild to build a document text matrix.
38 :    
39 :     2005-10-02 Ingo Feinerer <h0125130@wu-wien.ac.at>
40 :
