420 :    
421 :     * R/textdoccol.R: One can build term-document matrices if
422 :     nessecary (with buildTDM(...)) and fill the field tdm from a text
423 :     document collection with it.
424 :    
425 :     * R/textmatrix.R: Wrote S4 class for term-document matrices.

428 :    
429 :     * R/textdoccol.R: We now can read in a whole XML file with several
430 :     news items.
431 :    
432 : feinerer 17 2005-11-05 Ingo Feinerer <h0125130@wu-wien.ac.at>
433 :    
434 :     * R/textdoccol.R: Set up an S4 class for a collection of text
435 :     documents. A first attempt to read in XML input (like the RCV1
436 :     set) was made.
437 :    
438 :     * R/textdocument.R: Set up an S4 class for text documents. Wrote
439 :     some accessor functions.
440 :    
441 :     * data/newsitem.xml: Added this XML file for testing purposes. It
442 :     contains a single news item from the Reuters Corpus Volume 1
443 :     (RCV1) XML set.

446 :    
447 :     * R/textmatrix.R (textmatrix): Removed the transpose of the original
448 :     textmatrix as k-means clustering provided by R (kmeans) now works on
449 :     this textmatrix. The result is a k-means text clustering with a
450 :     similarity measure based upon word frequences.

453 :    
454 :     * R/textmatrix.R: Adapted the preprocessing code from the R
455 :     package "lsa" written by Fridolin Wild to build a document text matrix.
