The ls()
function allows us to look at a list of all of the objects, such
as data and functions, that we have saved so far. The rm()
function can be
used to delete any that we don’t want.
> ls()
[1] "x" "y"
> rm(x, y)
> ls()
character (0)
It’s also possible to remove all objects at once:
rm(list=ls())
