1233 :    
1234 : feinerer 22 * R/textdoccol.R: Constructor of textdoccol allows import of CSV
1235 :     files. See the questionnaire data/Umfrage.csv for such an example.
1236 : feinerer 23 We are now able to import files in Reuters-21578 XML format.
1237 : feinerer 22
1238 : feinerer 799 * Changed class interfaces in various files. Weighting of the text
1239 : feinerer 21 matrix is now possible.

1242 :    
1243 :     * R/textdoccol.R: One can build term-document matrices if
1244 :     nessecary (with buildTDM(...)) and fill the field tdm from a text
1245 :     document collection with it.
1246 :    
1247 :     * R/textmatrix.R: Wrote S4 class for term-document matrices.
1248 :

1254 : feinerer 17 2005-11-05 Ingo Feinerer <h0125130@wu-wien.ac.at>
1255 :    
1256 :     * R/textdoccol.R: Set up an S4 class for a collection of text
1257 :     documents. A first attempt to read in XML input (like the RCV1
1258 :     set) was made.
1259 :    
1260 :     * R/textdocument.R: Set up an S4 class for text documents. Wrote
1261 :     some accessor functions.
1262 :    
1263 :     * data/newsitem.xml: Added this XML file for testing purposes. It
1264 :     contains a single news item from the Reuters Corpus Volume 1
1265 :     (RCV1) XML set.

1268 :    
1269 :     * R/textmatrix.R (textmatrix): Removed the transpose of the original
1270 :     textmatrix as k-means clustering provided by R (kmeans) now works on
1271 :     this textmatrix. The result is a k-means text clustering with a
1272 :     similarity measure based upon word frequences.

1275 :    
1276 :     * R/textmatrix.R: Adapted the preprocessing code from the R
1277 :     package "lsa" written by Fridolin Wild to build a document text matrix.
