Hi all,
Suppose I have to letters 'u' and 'd'. Now I want to find all
combinations like that :
uuuuuu
uuuuud
uuuudu
.........
........
dddddd
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?
