1222 :    
1223 :     * R/textdoccol.R: Set up an S4 class for a collection of text
1224 :     documents. A first attempt to read in XML input (like the RCV1
1225 :     set) was made.
1226 :    
1227 :     * R/textdocument.R: Set up an S4 class for text documents. Wrote
1228 :     some accessor functions.
1229 :    
1230 :     * data/newsitem.xml: Added this XML file for testing purposes. It
1231 :     contains a single news item from the Reuters Corpus Volume 1
1232 :     (RCV1) XML set.

1235 :    
1236 :     * R/textmatrix.R (textmatrix): Removed the transpose of the original
1237 :     textmatrix as k-means clustering provided by R (kmeans) now works on
1238 :     this textmatrix. The result is a k-means text clustering with a
1239 :     similarity measure based upon word frequences.

1244 :     package "lsa" written by Fridolin Wild to build a document text matrix.
