rm can be used to remove objects. These can be specified successively as character strings, or in the character vector
list, or through a combination of both. All objects thus specified will be removed.
envir is NULL then the currently active environment is searched first.
TRUE then parents of the supplied directory are searched until a variable with the given name is encountered. A warning is printed for each variable that is not found.
remove(..., list = character(), pos = -1, envir = as.environment(pos), inherits = FALSE) rm (..., list = character(), pos = -1, envir = as.environment(pos), inherits = FALSE)
- the objects to be removed, as names (unquoted) or character strings (quoted).
- a character vector naming objects to be removed.
- where to do the removal. By default, uses the current environment. See ‘details’ for other possibilities.
environmentto use. See ‘details’.
- should the enclosing frames of the environment be inspected?
pos argument can specify the environment from which to remove the objects in any of several ways: as an integer (the position in the
search list); as the character string name of an element in the search list; or as an
environment (including using
sys.frame to access the currently active function calls). The
envir argument is an alternative way to specify an environment, but is primarily there for back compatibility.
It is not allowed to remove variables from the base environment and base namespace, nor from any environment which is locked (see
Earlier versions of R incorrectly claimed that supplying a character vector in
... removed the objects named in the character vector, but it removed the character vector. Use the
list argument to specify objects via a character vector.
