14 :    
15 :     * inst/doc/clustering.Rnw: Wrote a small vignette to present the

18 : feinerer 33 2005-12-15 Ingo Feinerer <h0125130@wu-wien.ac.at>
19 :    
20 :     * R/aobjects.R: Changed package document structure to avoid class

32 :    
33 :     * src/: Various splits can now be easily created for the

46 : feinerer 22 * R/textdoccol.R: Constructor of textdoccol allows import of CSV
47 :     files. See the questionnaire data/Umfrage.csv for such an example.
48 : feinerer 23 We are now able to import files in Reuters-21578 XML format.
49 : feinerer 22
50 : feinerer 21 * Changed class interfaces in various files. Weighting of the text
51 :     matrix is now possible.
52 :    
53 : feinerer 20 2005-11-08 Ingo Feinerer <h0125130@wu-wien.ac.at>
54 :    
55 :     * R/textdoccol.R: One can build term-document matrices if
56 :     nessecary (with buildTDM(...)) and fill the field tdm from a text
57 :     document collection with it.
58 :    
59 :     * R/textmatrix.R: Wrote S4 class for term-document matrices.
60 :    
61 : feinerer 19 2005-11-06 Ingo Feinerer <h0125130@wu-wien.ac.at>
62 :    
63 :     * R/textdoccol.R: We now can read in a whole XML file with several
64 :     news items.
65 :    
66 : feinerer 17 2005-11-05 Ingo Feinerer <h0125130@wu-wien.ac.at>
67 :    
68 :     * R/textdoccol.R: Set up an S4 class for a collection of text
69 :     documents. A first attempt to read in XML input (like the RCV1
70 :     set) was made.
71 :    
72 :     * R/textdocument.R: Set up an S4 class for text documents. Wrote
73 :     some accessor functions.
74 :    
75 :     * data/newsitem.xml: Added this XML file for testing purposes. It
76 :     contains a single news item from the Reuters Corpus Volume 1

79 : feinerer 16 2005-10-07 Ingo Feinerer <h0125130@wu-wien.ac.at>
80 :    
81 :     * R/textmatrix.R (textmatrix): Removed the transpose of the original
82 :     textmatrix as k-means clustering provided by R (kmeans) now works on
83 :     this textmatrix. The result is a k-means text clustering with a
84 :     similarity measure based upon word frequences.
85 :    
86 :     2005-10-05 Ingo Feinerer <h0125130@wu-wien.ac.at>
87 :
