meta

Get or set object metadata

Description

Get or set the object metadata in a corpus, tokens, dfm, or dictionary object. With the exception of dictionaries, this will be corpus-level metadata.

Usage

meta(x, field = NULL, type = c("user", "object", "system", "all"))

meta(x, field = NULL) <- value

Arguments

`x`	an object for which the metadata will be read or set
`field`	metadata field name(s); if `NULL` (default), return all metadata names
`type`	`"user"` for user-provided corpus-level metadata; `"system"` for metadata set automatically when the corpus is created; or `"all"` for all metadata.
`value`	new value of the metadata field

Value

For meta, a named list of the metadata fields in the corpus.

For meta <-, the corpus with the updated user-level metadata. Only user-level metadata may be assigned.

Examples

meta(data_corpus_inaugural)
meta(data_corpus_inaugural, "source")
meta(data_corpus_inaugural, "citation") <- "Presidential Speeches Online Project (2014)."
meta(data_corpus_inaugural, "citation")
