852            * R/termdocmatrix.R (textvector): Stemming is now performed before
853            erasing stopwords.
854            (weightMatrix): Adapted to handle sparse matrices.
855            (TermDocMatrix): Sparse matrix is now efficiently built by

859    
860            * DESCRIPTION: Replaced \pkg{filehashSQLite} with \pkg{filehash}
