Description Usage Arguments Value References Examples

The function translates the hierarchy defintion given into a data frame with one row for each file, including the generated document ID.

corpus_files(
  dir,
  hierarchy = list(),
  fsep = .Platform$file.sep,
  full_list = FALSE
)

`dir`	File path to the root directory of the text corpus, or a TIF[1] compliant data frame.
`hierarchy`	A named list of named character vectors describing the directory hierarchy level by level. If `TRUE` instead, the hierarchy structure is taken directly from the directory tree. See section Hierarchy of `readCorpus` for details.
`fsep`	Character string defining the path separator to use.
`full_list`	Logical, see return value.

Either a data frame with columns doc_id, file, path and one further factor column for each hierarchy level, or (if full_list=TRUE) a list containing that data frame (all_files) and also data frames describing the hierarchy by given names (hier_names), directories (hier_dirs) and relative paths (hier_paths).
