removeSparseTerms(x, sparse)
Arguments
x
A DocumentTermMatrix or a TermDocumentMatrix
sparse
A numeric for the maximal allowed sparsity in the range
from bigger zero to smaller one.
Value
A term-document matrix where those terms from x are removed
which have at least a sparse percentage of empty
(i.e., terms occurring 0 times in a document) elements. I.e.,
the resulting matrix contains only terms with a sparse factor
of less than sparse

data("crude")
require(tm)
