Can a global variable in R be accessed from within a function?
- Yes, a global variable can be accessed from within a function
- No, global variables are only accessible outside of functions
- It depends on the scoping rules applied within the function
- None of the above
Yes, a global variable in R can be accessed from within a function. The scoping rules in R allow functions to access variables defined in the global environment. However, if a variable with the same name is defined within the function's local environment, it will take precedence over the global variable.
