[R] recover lost global function

[Sam Steingold]

Since R has the same namespace for functions and variables,
> c <- 1
kills the global function, which can be restored by
> c <- get("c",mode="function")

Is there a way to prevent R from overriding globals
or at least warning when I do that
or at least warning when I replace a functional value with non-functional?

thanks.
