##### Remove Sparse Terms from a Term-Document Matrix

Remove sparse terms from a document-term or term-document matrix.

##### Usage

`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`

.

##### Examples

```
# NOT RUN {
data("crude")
tdm <- TermDocumentMatrix(crude)
removeSparseTerms(tdm, 0.2)
# }
```
