You want to remove unneeded variables or functions from your workspace or to erase its contents completely.
To delete or remove a variables from your workspace, you can use the rm function. The rm function removes a variable permanently from the workspace.
Let’s create some variables.
> a <- 5 > b <- 10 > c <- a + b > f <- function(n, p) sqrt(p * (1-p) / n)
Now, let’s say you want to remove the a variable. You can do it like this
You can also remove several variables at once.
> rm(b, c, f)
You can even erase your entire workspace at once. The rm function has a list argument consisting of a vector of names of variables to remove. Previously we saw that ls function returns a vector of variable names. So we can combine rm and ls to erase everything.
> ls()  "a" "b" "c" "f" > rm(list = ls()) > ls() character(0)
To remove the variables you can also use the broom icon at the top of the environment pane in RStudio.
