Rarefaction analysis plots the value of a measured quantity (call it R) against. For example, if we have a vector that contains 1, 2, 3, 4, 5 and we want to repeat this random sample five times then replicate(5,x) can be used and the output will be matrix of the below form: If you want to compare your samples to each other, then you must rarefy. email: Version 1.0, 06/10/05 Examples Subsample to 500 organisms (from over 500 organisms) for 12 samples. Rarify learns and optimizes workflows, automatically coordinating seating, order entry, food and beverage prep and delivery. rarify function: R function to rarify (subsample) a macroinvertebrate sample down to a fixed count by John Van Sickle, USEPA. Instantly all your teams, processes and actions are in perfect sync. With Rarify, they’re as simple and connected as the apps on your phone. This makes it possible for random functions, such as sample (), rnorm (), runif () and lots of others, to always return the same result, Example: set.seed (42) rnorm (3) 1 1.3709584 -0.5646982 0.3631284 set.seed (42) rnorm (3) 1 1.3709584 -0.5646982 0.3631284. The random sample can be repeated by using replicate function in R. The tools to transform service and experience don’t have to be complicated.
