file.show {base}R Documentation

Display One or More Files

Description

This function provides the core of the R help system, but it can be used for other purposes as well.

Usage

file.show(..., header, title="R Information",
          delete.file=FALSE, pager=getOption("pager"))

Arguments

... one or more character vectors containing the names of the files to be displayed.
header vector (of the same length as the number of files specified in ...) giving a header for each file being displayed. Defaults to empty strings.
title an overall title for the display. If a separate window is used for the display, title will be used as the window title.
delete.file should the files be deleted after display? Used for temporary files.
pager the pager to be used.

Note

How the pager is implemented is system dependent. At present the Unix version concatentates files and displays them in the pager set by the pager option setting. However, a GUI model might be to put up a file in a separate window and let the user leave it up while R continues running.
