[R] Global variables

[abhagwat]

Well, what would be really helpful is to restrict the scope of all
non-function variables, but keep a global for scope of all function
variables. Then, you still have access to all loaded functions, but you
don't mix up variables.

How would one do that?

Yes, but you probably shouldn't.  You would do it by setting the 
environment of the function to something that doesn't have the global 
environment as a parent, or grandparent, etc.  The only common examples 
of that are baseenv() and emptyenv().  For example,

x <- 1
f <- function() print(x)
