Using R, variadically checking if `exists`

Question

I would like to wrap R::base function exists into a wrapper function to make it more C-based and variadic in nature.

### current examples of `exists` usage

if(!exists(".humanVerse")) { initMemory(); }

#############################

if(!exists("path", .GlobalEnv$.humanVerse) || purge.memory)
        {  
        ### do something here
        }

#############################

if(exists(save.key, .GlobalEnv$.humanVerse[["colors"]][["dataframes"]]))
            {
            return( .GlobalEnv$.humanVerse[["colors"]][["dataframes"]][[save.key]] );
            }

The above examples work fine, in the order applied. But if I wanted to write a function to capture or trap the non-existent key, it will cause a problem.

exists("not.created");

whereas

checkExists = function(x)
    {
    exists(x);  
    }

checkExists(not.created);

throws an object not found error. Of course, I recognize that the "string" form of "not.created" is different than a variadic form.

I am looking for a way for the checkExists function to work.

The x in exists looks for a name, a character vector. What if I want to checkExists on an object, not a character? That is the essence of the variadic question.

Maybe I am merely asking how to capture the character name of the object? I don't know. R::base logic contorts my logic from time to time.
