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

## Description

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

## Usage

removeSparseTerms(x, sparse)

## Arguments

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)
# }
