Jadi kita dapat mengambil argumen apa pun, katakanlah, 1 atau 123 atau 300 atau 12345 untuk mendapatkan angka acak yang dapat direproduksi. Juga, dalam paketTeachingDemos, fungsi char2seed memungkinkan pengguna untuk mengatur seed berdasarkan string karakter. in an earlier R version (for reproducibility). set.seed is the recommended way to specify seeds. If kind is a character string, set R's RNG to the kind desired. the seed and the uniform and normal generators used when a random experiment is Programs to set random number generator (and seed) in R and S. Usage. This is a critical aspect of reproducible research.

You should always set the random number seed when conducting a simulation! Another alternative is to use set.seed() at the same checkpointing intervals (e.g. a different sequential value for each in a series of simulations) -- that might run the risk of a slightly higher correlation between successive simulations (I'm not sure what can be guaranteed about the properties of sequences from neighboring seeds) .

The set.seed() function sets the starting number used to generate a sequence of random numbers – it ensures that you get the same result if you start with that same seed each time you run the same process. For example, if I use the sample() function immediately after setting a seed, I will always get the same sample. set.seed(1) sample(3) ## [1] 1 3 2

R语言set.seed()函数的意义以及用法 A diferença em usar números distintos no set.seed() é basicamente que cada vez que você usar um número diferente nos parênteses será gerado um número aleatório diferente.
