Hi all, Suppose I have a population of 3 alphabets : A, B, C. From this population, number of ways that any 2 can be chosen is 3 i.e. AB, AC, and BC. Is there any R function to generalize this process, for any number of alphabets/numbers and for any sub-sample size? Thanks and regards, --------------------------------- [[alternative HTML version deleted]]
