## Combine Corpora, Documents, Term-Document Matrices, and Term Frequency Vectors

### Description

Combine several corpora into a single one, combine multiple documents into a corpus, combine multiple term-document matrices into a single one, or combine multiple term frequency vectors into a single term-document matrix.

### Usage

    ## S3 method for class 'VCorpus'
    c(..., recursive = FALSE)
    ## S3 method for class 'TextDocument'
    c(..., recursive = FALSE)
    ## S3 method for class 'TermDocumentMatrix'
    c(..., recursive = FALSE)
    ## S3 method for class 'term_frequency'
    c(..., recursive = FALSE)

### Arguments

`...` | Corpora, text documents, term-document matrices, or term frequency vectors.
`recursive` | Not used.

### See Also

`VCorpus`, `TextDocument`, `TermDocumentMatrix`, and `termFreq`.

### Examples

    data("acq")
    data("crude")
    meta(acq, "comment", type = "corpus") <- "Acquisitions"
    meta(crude, "comment", type = "corpus") <- "Crude oil"
    meta(acq, "acqLabels") <- 1:50
    meta(acq, "jointLabels") <- 1:50
    meta(crude, "crudeLabels") <- letters[1:20]
    meta(crude, "jointLabels") <- 1:20
    c(acq, crude)
    meta(c(acq, crude), type = "corpus")
    meta(c(acq, crude))
    c(acq[[30]], crude[[10]])
    c(TermDocumentMatrix(acq), TermDocumentMatrix(crude))
