tidy.Corpus

From tidytext v0.1.3 by Julia Silge

Tidy a Corpus object from the tm package

Tidy a Corpus object from the tm package. Returns a data frame with one-row-per-document, with a text column containing the document's text, and one column for each local (per-document) metadata tag. For corpus objects from the quanteda package, see tidy.corpus.

Usage

# S3 method for Corpus
tidy(x, collapse = "\n", ...)

Arguments

x: A Corpus object, such as a VCorpus or PCorpus
collapse: A string that should be used to collapse text within each corpus (if a document has multiple lines). Give NULL to not collapse strings, in which case a corpus will end up as a list column if there are multi-line documents.
...: Extra arguments, not used

Examples

# NOT RUN {
library(dplyr)   # displaying tbl_dfs

if (requireNamespace("tm", quietly = TRUE)) {
  library(tm)
  #' # tm package examples
  txt <- system.file("texts", "txt", package = "tm")
  ovid <- VCorpus(DirSource(txt, encoding = "UTF-8"),
                  readerControl = list(language = "lat"))

  ovid
  tidy(ovid)

  # choose different options for collapsing text within each
  # document
  tidy(ovid, collapse = "")$text
  tidy(ovid, collapse = NULL)$text

  # another example from Reuters articles
  reut21578 <- system.file("texts", "crude", package = "tm")
  reuters <- VCorpus(DirSource(reut21578),
                     readerControl = list(reader = readReut21578XMLasPlain))
  reuters

  tidy(reuters)
}
