file.edit | R Documentation |
Edit one or more files in a text editor.
file.edit(..., title = file, editor = getOption("editor"), fileEncoding = "")
... |
one or more character vectors containing the names of the
files to be displayed. These will be tilde-expanded: see
|
title |
the title to use in the editor; defaults to the filename. |
editor |
the text editor to be used, usually as a character string naming (or giving the path to) the text editor you want to use See ‘Details’. |
fileEncoding |
the encoding to assume for the file: the default
is to assume the native encoding. See the ‘Encoding’ section
of the help for |
The behaviour of this function is very system-dependent. Currently files can be opened only one at a time on Unix; on Windows, the internal editor allows multiple files to be opened, but has a limit of 50 simultaneous edit windows.
The title
argument is used for the window caption in Windows,
and is currently ignored on other platforms.
Any error in re-encoding the files to the native encoding will cause the function to fail.
The default for editor
is system-dependent. On
Windows it defaults to "internal"
, the script editor, and in
the macOS GUI the document editor is used whatever the value of
editor
. On Unix the default is set from the environment
variables EDITOR or VISUAL if either is set, otherwise
vi
is used.
editor
can also be an R function, in which case it is called
with the arguments name
, file
, and title
. Note
that such a function will need to independently implement all
desired functionality.
On Windows, UTF-8-encoded paths not valid in the current locale can be used.
