Does the following help: > set.seed(1) > pop <- 1:100 > s1 <- sample(pop, 5) > s1. <- pop[!(pop %in% s1)] > s2 <- sample(s1., 5) > s1 [1] 27 37 57 89 20 > s2 [1] 91 94 66 62 6 > spencer graves

Hello, I have a problem to treat my data. I seek the orders being able to treat under sampling: I have X samples divided into 10. How to take, in a random way, under sample from the 1st sample, and in addition, one under sample of the 2nd sample, and so on to X to calculate the average taxonomic richness of the selection. Then I would like to know how to renew the experiment by taking this time 2, 3... X under samples at the same time, always in a random way. Thank you in advance for your answer. Manue.
