Data:Matrix holding the sparse
matrix.Weighting:character containing
the mode which was applied on the matrix. Possible are term
frequency "term frequency", term frequency-inverse document frequency
"term frequency - inverse document frequency", binary
"binary" and logical "logical".signature(object = "TermDocMatrix"): Return the
sparse matrix.signature(object = "TermDocMatrix"): Sets the
sparse matrix.signature(object = "TermDocMatrix"): Returns the
weighting mode.signature(object = "TermDocMatrix"): Sets the
weighting mode.Ingo Feinerer
