Re: [R] random sampling with levels and with replacement

Hi, I am not perfectly sure what you want to do, but here is what I would do to maintain good/bad ratio in the sample (as Daniel posted, split the data and sample from the groups): df <- data.frame(V1 = 1:400, V2 = c(rep("good",360), rep("bad",40))) isGood <- which(df$V2=="good") isBad <- whi

Re: [R] random sampling with levels and with replacement

If you want perfect equality, split the data in good and bad and sample from the two samples individually. On average, however, random sampling from the entire data will reproduce the proportion of good and bad in the data. hth, Daniel -- View this message in context: http://r.789695.n4.nabbl
