422 :     * Wrote R documentation for some classes and methods.

425 :    
426 : feinerer 22 * R/textdoccol.R: Constructor of textdoccol allows import of CSV
427 :     files. See the questionnaire data/Umfrage.csv for such an example.
428 : feinerer 23 We are now able to import files in Reuters-21578 XML format.
429 : feinerer 22
430 : feinerer 21 * Changed class interfaces in various files. Weighting of the text
431 :     matrix is now possible.

433 : feinerer 20 2005-11-08 Ingo Feinerer <h0125130@wu-wien.ac.at>
434 :    
435 :     * R/textdoccol.R: One can build term-document matrices if
436 :     nessecary (with buildTDM(...)) and fill the field tdm from a text
437 :     document collection with it.
438 :    
439 :     * R/textmatrix.R: Wrote S4 class for term-document matrices.
440 :    
441 : feinerer 19 2005-11-06 Ingo Feinerer <h0125130@wu-wien.ac.at>
442 :    
443 :     * R/textdoccol.R: We now can read in a whole XML file with several
444 :     news items.
445 :    
446 : feinerer 17 2005-11-05 Ingo Feinerer <h0125130@wu-wien.ac.at>
447 :    
448 :     * R/textdoccol.R: Set up an S4 class for a collection of text
449 :     documents. A first attempt to read in XML input (like the RCV1
450 :     set) was made.
451 :    
452 :     * R/textdocument.R: Set up an S4 class for text documents. Wrote
453 :     some accessor functions.
454 :    
455 :     * data/newsitem.xml: Added this XML file for testing purposes. It
456 :     contains a single news item from the Reuters Corpus Volume 1
457 :     (RCV1) XML set.

459 : feinerer 16 2005-10-07 Ingo Feinerer <h0125130@wu-wien.ac.at>
460 :    
461 :     * R/textmatrix.R (textmatrix): Removed the transpose of the original
462 :     textmatrix as k-means clustering provided by R (kmeans) now works on
463 :     this textmatrix. The result is a k-means text clustering with a
464 :     similarity measure based upon word frequences.
465 :    
466 :     2005-10-05 Ingo Feinerer <h0125130@wu-wien.ac.at>
467 :    
468 :     * R/textmatrix.R: Adapted the preprocessing code from the R
469 :     package "lsa" written by Fridolin Wild to build a document text matrix.
470 :    
471 :     2005-10-02 Ingo Feinerer <h0125130@wu-wien.ac.at>
472 :
