Dear R users, I want to replicate sampled rows in data frame. The sampling results must be in this form:
a b Rep [1,] 3 4.0 R1 [2,] 6 8.0 R1 [3,] 1 0.1 R2 [4,] 6 8.0 R2 [5,] 1 0.1 R3 [6,] 5 7.0 R3 I have a code but I didn't succeed to insert to rep column. This is my code: a<-c(1,2,3,4,5,6) b<-c(0.1, 0.2, 4, 6, 7, 8) ab<-cbind(a, b) x<-replicate(3, sample(1:nrow(ab), 2)) aa<-ab[x, ] Please help me to solve that problem! Thank you very much!
