[R] last 2 questions about save and load

[markleeds at verizon.net]

i played around and i get the hang of save and load. I just
have two final questions :

1) is loading the RandomFields package the only
way to check if a file ( created through the save function )
is out there or not ? Because, I generally won't know if one has
been created yet or not.

2) Suppose, you have the case where you
created and saved a file. When you do an ls()
without loading that file, it doesn't show up in the list
obviously. So, if you want to delete that file for whatever
reason, is it possible ? Thanks.
