24 : feinerer 22 * R/textdoccol.R: Constructor of textdoccol allows import of CSV
25 :     files. See the questionnaire data/Umfrage.csv for such an example.
26 : feinerer 23 We are now able to import files in Reuters-21578 XML format.
27 : feinerer 22
28 : feinerer 21 * Changed class interfaces in various files. Weighting of the text
29 :     matrix is now possible.

31 : feinerer 20 2005-11-08 Ingo Feinerer <h0125130@wu-wien.ac.at>
32 :    
33 :     * R/textdoccol.R: One can build term-document matrices if
34 :     nessecary (with buildTDM(...)) and fill the field tdm from a text
35 :     document collection with it.
36 :    
37 :     * R/textmatrix.R: Wrote S4 class for term-document matrices.
38 :    
39 : feinerer 19 2005-11-06 Ingo Feinerer <h0125130@wu-wien.ac.at>
40 :    
41 :     * R/textdoccol.R: We now can read in a whole XML file with several
42 :     news items.
43 :    
44 : feinerer 17 2005-11-05 Ingo Feinerer <h0125130@wu-wien.ac.at>
45 :    
46 :     * R/textdoccol.R: Set up an S4 class for a collection of text
47 :     documents. A first attempt to read in XML input (like the RCV1
48 :     set) was made.
49 :    
50 :     * R/textdocument.R: Set up an S4 class for text documents. Wrote
51 :     some accessor functions.
52 :    
53 :     * data/newsitem.xml: Added this XML file for testing purposes. It
54 :     contains a single news item from the Reuters Corpus Volume 1

57 : feinerer 16 2005-10-07 Ingo Feinerer <h0125130@wu-wien.ac.at>
58 :    
59 :     * R/textmatrix.R (textmatrix): Removed the transpose of the original
60 :     textmatrix as k-means clustering provided by R (kmeans) now works on
61 :     this textmatrix. The result is a k-means text clustering with a
62 :     similarity measure based upon word frequences.
63 :    
64 :     2005-10-05 Ingo Feinerer <h0125130@wu-wien.ac.at>
65 :    
66 :     * R/textmatrix.R: Adapted the preprocessing code from the R
67 :     package "lsa" written by Fridolin Wild to build a document text matrix.
68 :    
69 :     2005-10-02 Ingo Feinerer <h0125130@wu-wien.ac.at>
70 :
