In R, the environment is a collection of objects like functions, variables, data frame, etc.
R opens an environment each time Rstudio is prompted.
The top-level environment available is the global environment, called R_GlobalEnv. And we have the local environment.
We can list the content of the current environment.
ls(environment())
Output
## [1] "diff_ts" "dt" "speed" "square_function"
## [5] "ts" "x" "x_vector"
