| edit {utils} | R Documentation |
Invoke a text editor on an R object.
## Default S3 method:
edit(name = NULL, file = "", editor = getOption("editor"), ...)
vi(name = NULL, file = "")
emacs(name = NULL, file = "")
pico(name = NULL, file = "")
xemacs(name = NULL, file = "")
xedit(name = NULL, file = "")
name |
a named object that you want to edit. If name is missing
then the file specified by file is opened for editing. |
file |
a string naming the file to write the edited version to. |
editor |
a string naming the text editor you want to use. On
Unix the default is set from the environment variables EDITOR
or VISUAL if either is set, otherwise vi is used. On
Windows it defaults to notepad. |
... |
further arguments to be passed to or from methods. |
edit invokes the text editor specified by editor with
the object name to be edited. It is a generic function,
currently with a default method and one for data frames and matrices.
data.entry can be used to edit data, and is used by edit
to edit matrices and data frames on systems for which
data.entry is available.
It is important to realize that edit does not change the object
called name. Instead, a copy of name is made and it is that copy
which is changed. Should you want the changes to apply to the object
name you must assign the result of edit to
name. (Try fix if you want to make permanent
changes to an object.)
In the form edit(name),
edit deparses name into a temporary file and invokes the
editor editor on this file. Quitting from the editor causes
file to be parsed and that value returned.
Should an error occur in parsing, possibly due to incorrect syntax, no
value is returned. Calling edit(), with no arguments, will
result in the temporary file being reopened for further editing.
The functions vi, emacs, pico, xemacs,
xedit rely on the corresponding editor being available and
being on the path. This is system-dependent.
