[R] [OT] Combinatorials wtih constraints

2010-06-24 Thread Doran, Harold
This is not an R question, but a question on some combinatorial mathematics. Apologies for the OT if it is wildy inappropriate. The traditional C(n.k) method tells me how many combinations k I can make with n objects. However, suppose I want the number of combinations where an object cannot be u
