This sounds suspiciously like homework (which is off-topic... see the Posting
Guide), and you haven't indicated how you plan to encode your poker hands, and

understand these other techniques and R then you should be able to do this
already.
If this is not homework, then please show your work so far instead of showing a
completely different example.
