It's very sad that there is no matlab function "npermsk".
Not work for R is long, and k is small.
For example, R = 1:100, k = 2.
@li haitao, the max digital is 9. If length of R great than 10, it is another problem. I think you can submit a problem like this but larger R.
@ Binbin Qi, You're right.
