With what we have seen so far, it is possible to make already simple calculations, define and modify variables. There is still a lot to follow and it is important to have some basic tools to keep things tidy. One of such tools is the possibility to see defined variables and eventually remove unused ones.

# List all variables ls() # hidden variable starts with dot ls(all.names = TRUE) # shows all # Remove a variable rm(x.1) # removes the variable x.1 ls() # x.1 is not there any more rm(list = ls()) # removes all variables ls()
