How to randomize a vector
I would like to randomly reorganize the order of the numbers in a vector, in a simple one-line command?
My particular vector V has 150 entries for each value from 1 to 10:
V <- rep(1:10, each=150)
Yes.
sample(V)
From ?sample:
For ‘sample’ the default for ‘size’ is the number of items inferred from the first argument, so that ‘sample(x)’ generates a random permutation of the elements of ‘x’ (or ‘1:x’).
Use sample function
V<-rep(1:10, each=150)
set.seed(001) # just to make it reproducible
sample(V)
