3 :     * R/textdoccol.R: Removed bug that caused invalid text document
4 :     collections when handling many input files.
5 :    
6 : feinerer 36 2006-01-11 Ingo Feinerer <h0125130@wu-wien.ac.at>

8 : feinerer 37 * R/textdoccol.R: Restructured and extended file import
9 :     mechanism.
10 :    
11 : feinerer 36 * inst/doc/clustering.Rnw: Adapted vignette for use with
12 :     ReutNews.rda
13 :    
14 :     * man/ReutNews.Rd: Documentation for ReutNews.rda
15 :    
16 :     * data/ReutNews.rda: A tiny Reuters21578 example data set.
17 :    
18 : feinerer 34 2005-12-22 Ingo Feinerer <h0125130@wu-wien.ac.at>
19 :    
20 :     * inst/doc/clustering.Rnw: Wrote a small vignette to present the
21 :     clustering facilities of this package.

23 : feinerer 33 2005-12-15 Ingo Feinerer <h0125130@wu-wien.ac.at>
24 :    
25 :     * R/aobjects.R: Changed package document structure to avoid class

29 :    
30 : feinerer 29 * Wrote a script for the ModLewis Split for the Reuters-21578 XML
31 :     data set.
32 :    
33 : feinerer 28 * Finished documentation and reordered directory structure. Now "R
34 :     CMD check textmin" works without errors.
35 :    
36 : feinerer 27 2005-12-04 Ingo Feinerer <h0125130@wu-wien.ac.at>
37 :    
38 :     * src/: Various splits can now be easily created for the
39 :     Reuters21578 data set.

42 :    
43 :     * Updated documentation

50 :    
51 : feinerer 22 * R/textdoccol.R: Constructor of textdoccol allows import of CSV
52 :     files. See the questionnaire data/Umfrage.csv for such an example.
53 : feinerer 23 We are now able to import files in Reuters-21578 XML format.
54 : feinerer 22
55 : feinerer 21 * Changed class interfaces in various files. Weighting of the text
56 :     matrix is now possible.
57 :    
58 : feinerer 20 2005-11-08 Ingo Feinerer <h0125130@wu-wien.ac.at>
59 :    
60 :     * R/textdoccol.R: One can build term-document matrices if
61 :     nessecary (with buildTDM(...)) and fill the field tdm from a text
62 :     document collection with it.
63 :    
64 :     * R/textmatrix.R: Wrote S4 class for term-document matrices.
65 :    
66 : feinerer 19 2005-11-06 Ingo Feinerer <h0125130@wu-wien.ac.at>
67 :    
68 :     * R/textdoccol.R: We now can read in a whole XML file with several
69 :     news items.
70 :    
71 : feinerer 17 2005-11-05 Ingo Feinerer <h0125130@wu-wien.ac.at>
72 :    
73 :     * R/textdoccol.R: Set up an S4 class for a collection of text
74 :     documents. A first attempt to read in XML input (like the RCV1
75 :     set) was made.
76 :    
77 :     * R/textdocument.R: Set up an S4 class for text documents. Wrote
78 :     some accessor functions.
79 :    
80 :     * data/newsitem.xml: Added this XML file for testing purposes. It
81 :     contains a single news item from the Reuters Corpus Volume 1

84 : feinerer 16 2005-10-07 Ingo Feinerer <h0125130@wu-wien.ac.at>
85 :    
86 :     * R/textmatrix.R (textmatrix): Removed the transpose of the original
87 :     textmatrix as k-means clustering provided by R (kmeans) now works on
88 :     this textmatrix. The result is a k-means text clustering with a
89 :     similarity measure based upon word frequences.
90 :    
91 :     2005-10-05 Ingo Feinerer <h0125130@wu-wien.ac.at>
92 :    
93 :     * R/textmatrix.R: Adapted the preprocessing code from the R
