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 ls
to rm
.
rm(list = ls())
