If we randomly select some observations for any task in R or in any statistical software it results in different values all the time and this happens because of randomization. R语言set.seed()函数的意义以及用法. 醉一心 回复 weixin_44083877: 这个没有特殊的规定,只要保证两次种子一样就可以得到相同的结果. 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. Como a função do set.seed() é gerar números aleatórios, o valor utilizado seria uma forma de garantir que seja usado o mesmo número aleatório posteriormente, por exemplo: Se hela listan på set.seed()设置种子到底是啥作用? 主要作用:可重现一样的结果. R语言中set.seed()作用是设定生成随机数的种子,目的是为了让结果具有重复性,重现结果。 不设定种子不行吗?当然可以,但是结果就不能复现。如: 2018-01-22 · 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.

The use of set.seed is to make sure that we get the same results for randomization. If we randomly select some observations for any task in R or in any statistical software it results in different values all the time and this happens because of randomization. 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 basic installation of the R programming language provides the set.seed function. Within the set.seed function, we simply have to specify a numeric value to set a seed. Have a look at the following R code: set.seed(12345) # Set seed for reproducibility rpois (5, 3) # Generate random numbers with seed # 4 5 4 5 3 set.seed is a base function that it is able to generate (every time you want) together other functions (rnorm, runif, sample) the same random value. Below an example without set.seed This function obtain the .Random.seed object in the global environment. If it is absent, runif (1L) is called and then the seed is obtained. How to stop set.seed() besides exiting out of R?. Hi list, I am curious how to stop the set.seed(), I don't want the same repeated random number.
