DirSource

Directory Source

Description

Create a directory source.

Usage

DirSource(directory = ".",
          encoding = "",
          pattern = NULL,
          recursive = FALSE,
          ignore.case = FALSE,
          mode = "text")

Arguments

`directory`	A character vector of full path names; the default corresponds to the working directory `getwd()`.
`encoding`	a character string describing the current encoding. It is passed to `iconv` to convert the input to UTF-8.
`pattern`	an optional regular expression. Only file names which match the regular expression will be returned.
`recursive`	logical. Should the listing recurse into directories?
`ignore.case`	logical. Should pattern-matching be case-insensitive?
`mode`	a character string specifying if and how files should be read in. Available modes are: `""` No read. In this case `getElem` and `pGetElem` only deliver URIs. `"binary"` Files are read in binary raw mode (via `readBin`). `"text"` Files are read as text (via `readLines`).

Details

A directory source acquires a list of files via dir and interprets each file as a document.

Value

An object inheriting from DirSource, SimpleSource, and Source.

Examples

DirSource(system.file("texts", "txt", package = "tm"))
