RE: how to delete duplicate items in the same list

Sabrina,

For exact expressions try Union, which may reorder the items. If you don't
want reordering use UnsortedUnion, which is defined in the Union Help
examples. You will have to copy the definition into your notebook.

Hello, all:
I can't find a way to make sure all items in the same list are unique. Can
anybody help me out? Thanks a lot!

Sabrina
