Hi all,

Suppose I have to letters 'u' and 'd'. Now I want to find all combinations like that :


This type of combination generally required for Option Pricing in financial/derivative market. Here generally 'u' means: up-move and 'd' means down move of price like Stock price etc.

Is there any easy way in R for doing that?
