To remove variables from our R workspace, we can use the built-in
rm function. This method as a few options, so let's take a look at a few of them.
The first thing we can do, is remove one variable at a time. We simply pass the variable to the
rm function and it will be deleted.
x = 34 rm(x) print(x) # x is gone
We can also pass multiple valures to the
rm function and it will remove each of them.
x = 34 my.string = "Hello" rm(x, my.string)
Finally, we use the
ls method in a previous article. This
ls function return a list of all variables in our workspace. If we want to clear our workspace, we can pass the list from
rm(list = ls())
