Actually we don't need the createInOperator function -- You can just add the setMethod below after cast etc.

I see. I will modify soon. Thanks.

@shivaram I modified the position of setMethod for %in% operator. Could you review it?

[shivaram]

Could you write a slightly more detailed description of what this operator does ? It will be great to also have a short example (similar to what we have for cast)

[yu-iskw]

Sure!
