set.seed()作用. R语言中set.seed()作用是设定生成随机数的种子，种子是为了让结果具有重复性，重现结果。如果不设定种子，生成的随机数无法重现。 How to set a random seed in R for pseudo-random number generation.Thanks for watching!! ️♫ Eric Skiff - Chibi Ninjahttp://freemusicarchive.org/music/Eric_Sk Seeds in R. In base R there are two main objects to handle seeds: set.seed() and .Random.seed. For a vast number of problems it is enough to use set.seed(), which supplies an integer as a seed. The workflow, then, is as simple as follows: set.seed startet den R-Zufallsgenererator an einer bestimmten Stelle.

If we want to keep the values that are produced at first random selection then we can do this by storing them in an object after randomization or we can fix the randomization procedure so that we get the same results all the time.

The set.seed helps to create the replicate of the random generation. If the name of the object changes that does not mean the replication will be changed but if we change the position then it will. Here, in the below example x4 in the first random generation and the x_4 in the second random generation with the same set.seed are same but x4 and x4 in both are different. set.seed (seed) Set the seed of R ‘s random number generator, which is useful for creating simulations or random objects that can be reproduced.

Usage set.seed(seed, kind = NULL, normal.kind = NULL) Arguments Set.seed in R – Control Random Numbers R’s Random number generator. Random number generators are a common function found in programming languages and R is no Random number seed. A random number seed is an integer used by R’s random number generator to calculate the next number set.seed in r.
