Hi, there, Suppose I have two vector say x=c(1 2 3 4 5) and y=(2 3 6 7). Then I want to combine these two vector together and get z=c(1 2 3 4 5 6 7) with 2 and 3 only appear once. I want to extend this one to a general case(say more than 100 elements in x and y and each time I don't know which elements are the same). Do you happen to know how to do this and which command should use?
Thank you very much. Please reply to this email. Any kind help would be greatly appreciated.
