2 :    
3 :     * R/: Some cosmetic cleanups.
4 :    
5 :     * inst/: Removed vignette on clustering. That and much more is now
6 :     described in the JSS paper on text mining. Based upon that
7 :     article an elaborated vignette will be incorporated in the future.
8 :    
9 : feinerer 42 2006-07-01 Ingo Feinerer <h0125130@wu-wien.ac.at>

45 :    
46 :     * R/aobjects.R: Changed package document structure to avoid class

50 :    
51 : feinerer 29 * Wrote a script for the ModLewis Split for the Reuters-21578 XML
52 :     data set.
53 :    
54 : feinerer 28 * Finished documentation and reordered directory structure. Now "R
55 :     CMD check textmin" works without errors.

57 : feinerer 27 2005-12-04 Ingo Feinerer <h0125130@wu-wien.ac.at>
58 :    
59 :     * src/: Various splits can now be easily created for the

63 :    
64 :     * Updated documentation

72 : feinerer 22 * R/textdoccol.R: Constructor of textdoccol allows import of CSV

74 : feinerer 23 We are now able to import files in Reuters-21578 XML format.
75 : feinerer 22
76 : feinerer 21 * Changed class interfaces in various files. Weighting of the text
77 :     matrix is now possible.

79 : feinerer 20 2005-11-08 Ingo Feinerer <h0125130@wu-wien.ac.at>
80 :    
81 :     * R/textdoccol.R: One can build term-document matrices if

84 :    
85 :     * R/textmatrix.R: Wrote S4 class for term-document matrices.
86 :    
87 : feinerer 19 2005-11-06 Ingo Feinerer <h0125130@wu-wien.ac.at>
88 :

93 :    
94 :     * R/textdoccol.R: Set up an S4 class for a collection of text

96 :     set) was made.
97 :    
98 :     * R/textdocument.R: Set up an S4 class for text documents. Wrote
99 :     some accessor functions.
100 :    
101 :     * data/newsitem.xml: Added this XML file for testing purposes. It
102 :     contains a single news item from the Reuters Corpus Volume 1
103 :     (RCV1) XML set.
104 :    
105 : feinerer 16 2005-10-07 Ingo Feinerer <h0125130@wu-wien.ac.at>
106 :    
107 :     * R/textmatrix.R (textmatrix): Removed the transpose of the original
108 :     textmatrix as k-means clustering provided by R (kmeans) now works on
109 :     this textmatrix. The result is a k-means text clustering with a
110 :     similarity measure based upon word frequences.
111 :    
112 :     2005-10-05 Ingo Feinerer <h0125130@wu-wien.ac.at>
113 :
