I realize that one uses
set.seed() in R for pseudo-random number generation. I also realize that using the same number, like
set.seed(123) insures you can reproduce results.
But what I don't get is what do the values themselves mean. I am playing with several functions, and some use
set.seed(12345). What does that number mean (if anything)- and when should I use a different one.
Example, in a book I am working through- they use
set.seed(12345) when creating a training set for decision trees. Then in another chapter, they are using
set.seed(300) for creating a Random Forest.
Just don't get the number.
