"For example" would be "e.g.", ("exempli gratia" in Latin.)
"E.g." is illustrative, whereas "i.e." is exhaustive.
I hadn't heard "i.e." expanded to "in example" before - that explains one source of misunderstanding (despite being grammatically incorrect in its own right).
Edit: It seems you've since been unfairly downvoted for explaining what you meant. Please folks, don't do that. I asked the question, and @fraserharris answered honestly.
