Dear all R-users, (My apologies if this subject is wrong) I have dataset: mydat <- as.data.frame( matrix(c(14,0,1,0,1,1, 25,1,1,0,1,1, 5,0,0,1,1,0, 31,1,1,1,1,1, 10,0,0,0,0,1), nrow=5,ncol=6,byrow=TRUE)) dimnames(mydat)[[2]] <-c("size","A","B","C","D","E") > mydat size A B C D E 1 14 0 1 0 1 1 2 25 1 1 0 1 1 3 5 0 0 1 1 0 4 31 1 1 1 1 1 5 10 0 0 0 0 1 > sum(mydat$size) [1] 85 >
where size is number of each row that have this combination of variables. In this dataset I have 85 tuples in expanded dataset. I want to generate random number between 1 and 85. Say, if the first random number is 15, so the number 15 is 1 1 0 1 1 then, if the next random number is 7, then 0 1 0 1 1 then if random number is 79 0 0 0 0 1 random number is 46 1 1 1 1 1 random number is 3 0 1 0 1 1 random number is 28 1 1 0 1 1 So, the result random tuples (order from 6 random number): 0 1 0 1 1 0 1 0 1 1 1 1 0 1 1 1 1 0 1 1 1 1 1 1 1 0 0 0 0 1 I would be very happy if anyone could help me. Thank you very much in advance.
