1214 :    
1215 :     * R/textdoccol.R: One can build term-document matrices if
1216 :     nessecary (with buildTDM(...)) and fill the field tdm from a text
1217 :     document collection with it.
1218 :    
1219 :     * R/textmatrix.R: Wrote S4 class for term-document matrices.

1221 : feinerer 19 2005-11-06 Ingo Feinerer <h0125130@wu-wien.ac.at>
1222 :    
1223 :     * R/textdoccol.R: We now can read in a whole XML file with several
1224 :     news items.
1225 :    
1226 : feinerer 17 2005-11-05 Ingo Feinerer <h0125130@wu-wien.ac.at>
1227 :    
1228 :     * R/textdoccol.R: Set up an S4 class for a collection of text
1229 :     documents. A first attempt to read in XML input (like the RCV1
1230 :     set) was made.
1231 :    
1232 :     * R/textdocument.R: Set up an S4 class for text documents. Wrote
1233 :     some accessor functions.
1234 :    
1235 :     * data/newsitem.xml: Added this XML file for testing purposes. It
1236 :     contains a single news item from the Reuters Corpus Volume 1
1237 :     (RCV1) XML set.

1240 :    
1241 :     * R/textmatrix.R (textmatrix): Removed the transpose of the original
1242 :     textmatrix as k-means clustering provided by R (kmeans) now works on
1243 :     this textmatrix. The result is a k-means text clustering with a
1244 :     similarity measure based upon word frequences.

1246 :     2005-10-05 Ingo Feinerer <h0125130@wu-wien.ac.at>
1247 :    
1248 :     * R/textmatrix.R: Adapted the preprocessing code from the R
1249 :     package "lsa" written by Fridolin Wild to build a document text matrix.
