e.g. I have a big data set called "combined", and then a small sample of "combined" called "miceSample". I wish to delete "miceSample" from "combined" to create a new smaller data set and store it into a new object. combined <- rbind(scaleMiceTrain, scaleMiceTest) miceSample <- sample(combined[,-c(1,2)],nvars, replace=FALSE) How do I do that? -- View this messa...
