How does the global environment in R interact with other environments like those within functions?
- Variables defined in the global environment can be accessed and modified from within functions
- Variables defined in the global environment cannot be accessed or modified from within functions
- Variables defined within functions are automatically added to the global environment
- The global environment is isolated from other environments in R
In R, the global environment interacts with other environments in such a way that variables defined in the global environment can be accessed and modified from within functions. This allows functions to utilize global variables as needed. However, variables defined within functions are not automatically added to the global environment, and changes made to global variables within functions may not persist outside of the function's execution.
