832 : feinerer 29 data set.
833 :    
834 : feinerer 799 * Finished documentation and reordered directory structure. Now "R
835 : feinerer 28 CMD check textmin" works without errors.

851 :    
852 : feinerer 22 * R/textdoccol.R: Constructor of textdoccol allows import of CSV
853 :     files. See the questionnaire data/Umfrage.csv for such an example.
854 : feinerer 23 We are now able to import files in Reuters-21578 XML format.
855 : feinerer 22
856 : feinerer 799 * Changed class interfaces in various files. Weighting of the text
857 : feinerer 21 matrix is now possible.

859 : feinerer 20 2005-11-08 Ingo Feinerer <h0125130@wu-wien.ac.at>
860 :    
861 :     * R/textdoccol.R: One can build term-document matrices if
862 :     nessecary (with buildTDM(...)) and fill the field tdm from a text
863 :     document collection with it.
864 :    
865 :     * R/textmatrix.R: Wrote S4 class for term-document matrices.
866 :    
867 : feinerer 19 2005-11-06 Ingo Feinerer <h0125130@wu-wien.ac.at>
868 :    
869 :     * R/textdoccol.R: We now can read in a whole XML file with several
870 :     news items.
871 :    
872 : feinerer 17 2005-11-05 Ingo Feinerer <h0125130@wu-wien.ac.at>
873 :    
874 :     * R/textdoccol.R: Set up an S4 class for a collection of text
875 :     documents. A first attempt to read in XML input (like the RCV1
876 :     set) was made.
877 :    
878 :     * R/textdocument.R: Set up an S4 class for text documents. Wrote
879 :     some accessor functions.
880 :    
881 :     * data/newsitem.xml: Added this XML file for testing purposes. It
882 :     contains a single news item from the Reuters Corpus Volume 1
883 :     (RCV1) XML set.

886 :    
887 :     * R/textmatrix.R (textmatrix): Removed the transpose of the original
888 :     textmatrix as k-means clustering provided by R (kmeans) now works on
889 :     this textmatrix. The result is a k-means text clustering with a
890 :     similarity measure based upon word frequences.
891 :    
892 :     2005-10-05 Ingo Feinerer <h0125130@wu-wien.ac.at>
893 :    
894 :     * R/textmatrix.R: Adapted the preprocessing code from the R
895 :     package "lsa" written by Fridolin Wild to build a document text matrix.
