loadtext: load a text file

In fdm2id: Data Mining and R Programming for Beginners

load a text file

Description

(Down)Load a text file (and extract it if it is in a zip file).

Usage

loadtext(
  file = NULL,
  dir = tempdir(),
  collapse = TRUE,
  sep = NULL,
  categories = NULL,
  cache = FALSE
)

Arguments

file	The path or URL of the text file. If not specified, defaults to an interactive file chooser (file.choose) when running interactively; in a non-interactive session (script, CI, R CMD check), file must be given explicitly.
dir	The directory the file is downloaded (and, for a zip archive, extracted) into. Defaults to the session's temporary directory, which is emptied when R exits. Pass an explicit path (together with cache = TRUE) to keep the downloaded corpus between sessions.
collapse	Indicates whether or not lines of each documents should collapse together or not.
sep	Separator between text fields.
categories	Columns that should be considered as categorical data.
cache	Whether the downloaded (and, for a zip archive, extracted) files are kept in dir and reused on the next call. They are deleted, and downloaded again every time, by default.

Value

The text contained in the dowloaded file.

Examples

# Not run automatically: this downloads a 31 MB archive from a third-party server, so it
# depends on both the network and that server staying up.
## Not run: 
text = loadtext ("http://mattmahoney.net/dc/text8.zip")
# Keep the archive between calls, in a directory of your choosing
text = loadtext ("http://mattmahoney.net/dc/text8.zip", dir = "~/corpora", cache = TRUE)

## End(Not run)
