Is there an easy way to see if an object exists in R? I would love a function that returns TRUE if the object has been defined and FALSE if the object has not been defined. Thus far, everything I try returns

Error: object 'asdf' not found

I want a function that returns TRUE if the argument exists (e.g., does.exist(asdf) ) and returns FALSE if it does not exist.

Any ideas if there is such a thing or how I would make it?

It does not return an error, it returns `FALSE` in that case, as documented. – joran Oct 19 '15 at 20:25

Aha. The issue was that I was omitting quotation marks. – tcarpenter Oct 19 '15 at 20:29
