423 :     * R/textdoccol.R: Set up an S4 class for a collection of text
424 :     documents. A first attempt to read in XML input (like the RCV1
425 :     set) was made.
426 :    
427 :     * R/textdocument.R: Set up an S4 class for text documents. Wrote
428 :     some accessor functions.

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