43 : feinerer 22 * R/textdoccol.R: Constructor of textdoccol allows import of CSV
44 :     files. See the questionnaire data/Umfrage.csv for such an example.
45 : feinerer 23 We are now able to import files in Reuters-21578 XML format.
46 : feinerer 22
47 : feinerer 21 * Changed class interfaces in various files. Weighting of the text
48 :     matrix is now possible.

50 : feinerer 20 2005-11-08 Ingo Feinerer <h0125130@wu-wien.ac.at>
51 :    
52 :     * R/textdoccol.R: One can build term-document matrices if
53 :     nessecary (with buildTDM(...)) and fill the field tdm from a text

55 :    
56 :     * R/textmatrix.R: Wrote S4 class for term-document matrices.
57 :    
58 : feinerer 19 2005-11-06 Ingo Feinerer <h0125130@wu-wien.ac.at>
59 :    
60 :     * R/textdoccol.R: We now can read in a whole XML file with several
61 :     news items.
62 :    
63 : feinerer 17 2005-11-05 Ingo Feinerer <h0125130@wu-wien.ac.at>
64 :    
65 :     * R/textdoccol.R: Set up an S4 class for a collection of text

67 :     set) was made.
68 :    
69 :     * R/textdocument.R: Set up an S4 class for text documents. Wrote
70 :     some accessor functions.
71 :    
72 :     * data/newsitem.xml: Added this XML file for testing purposes. It
73 :     contains a single news item from the Reuters Corpus Volume 1

76 : feinerer 16 2005-10-07 Ingo Feinerer <h0125130@wu-wien.ac.at>
77 :    
78 :     * R/textmatrix.R (textmatrix): Removed the transpose of the original
79 :     textmatrix as k-means clustering provided by R (kmeans) now works on
80 :     this textmatrix. The result is a k-means text clustering with a
81 :     similarity measure based upon word frequences.
82 :    
83 :     2005-10-05 Ingo Feinerer <h0125130@wu-wien.ac.at>
