1217 :    
1218 : feinerer 799 * Wrote R documentation for some classes and methods.

1221 :    
1222 : feinerer 22 * R/textdoccol.R: Constructor of textdoccol allows import of CSV
1223 :     files. See the questionnaire data/Umfrage.csv for such an example.
1224 : feinerer 23 We are now able to import files in Reuters-21578 XML format.
1225 : feinerer 22
1226 : feinerer 799 * Changed class interfaces in various files. Weighting of the text
1227 : feinerer 21 matrix is now possible.

1230 :    
1231 :     * R/textdoccol.R: One can build term-document matrices if
1232 :     nessecary (with buildTDM(...)) and fill the field tdm from a text
1233 :     document collection with it.
1234 :    
1235 :     * R/textmatrix.R: Wrote S4 class for term-document matrices.
1236 :    
1237 : feinerer 19 2005-11-06 Ingo Feinerer <h0125130@wu-wien.ac.at>
1238 :    
1239 :     * R/textdoccol.R: We now can read in a whole XML file with several
1240 :     news items.
1241 :    
1242 : feinerer 17 2005-11-05 Ingo Feinerer <h0125130@wu-wien.ac.at>
1243 :    
1244 :     * R/textdoccol.R: Set up an S4 class for a collection of text
1245 :     documents. A first attempt to read in XML input (like the RCV1
1246 :     set) was made.
1247 :    
1248 :     * R/textdocument.R: Set up an S4 class for text documents. Wrote
1249 :     some accessor functions.
1250 :    
1251 :     * data/newsitem.xml: Added this XML file for testing purposes. It
1252 :     contains a single news item from the Reuters Corpus Volume 1
1253 :     (RCV1) XML set.

1255 : feinerer 16 2005-10-07 Ingo Feinerer <h0125130@wu-wien.ac.at>
1256 :    
1257 :     * R/textmatrix.R (textmatrix): Removed the transpose of the original
1258 :     textmatrix as k-means clustering provided by R (kmeans) now works on
1259 :     this textmatrix. The result is a k-means text clustering with a
1260 :     similarity measure based upon word frequences.
1261 :    
1262 :     2005-10-05 Ingo Feinerer <h0125130@wu-wien.ac.at>
1263 :    
1264 :     * R/textmatrix.R: Adapted the preprocessing code from the R
1265 :     package "lsa" written by Fridolin Wild to build a document text matrix.
1266 :    
1267 :     2005-10-02 Ingo Feinerer <h0125130@wu-wien.ac.at>
1268 :
