But "miceSample" has multiple columns... For example if nvars=4, I have 4 columns of data to delete from "combined". Specifically, I have 187 columns in "combined", and "miceSample" only has 4 columns. So the new data frame should have 183 columns. -- View this message in context: http://r

Sorry to post multiple questions, but this is still related to the sample function. In my previous example, how do I save/store the current sample so when I run sample again (after analysis) I can exclude the samples that were previously chosen. For example if I have 180 factors or columns...an
