[R] error in exists.....

[Greg Snow]

You might try `hasName` instead of `exists` since `exists` is designed
for environments and `hasName` for objects (like lists).  Note that
the order of the arguments is switched between the 2 functions.
This does the same thing as Andrew Simmons' answer, but is a little bit shorter.
