ls {base}

R Documentation

List Objects

Description

ls and objects return a vector of character strings giving the names of the objects in the specified environment. When invoked with no argument at the top level prompt, ls shows what data sets and functions a user has defined. When invoked with no argument inside a function, ls returns the names of the functions local variables. This is useful in conjunction with browser.

Usage

ls(name, pos= -1, envir=pos.to.env(pos),
       all.names=FALSE, pattern)
objects(name, pos= -1, envir=pos.to.env(pos),
       all.names=FALSE, pattern)

Arguments

name	the name of an attached object appearing in the vector of names returned by search.
pos	the index of an attached object in the list returned by search. Defaults to the global environment.
envir	an evaluation environment. Defaults to the one corresponding to pos.
all.names	a logical value. If TRUE, all object names are returned. If FALSE, names which begin with a “.” are omitted.
