Select n from N Random Numbers
Suppose that you want to select (n=)10 individuals from (N=)736 individuals.
sample(736,10)
## [1] 690 620 48 384 534 437 216 731 68 448
Randomly Allocate N Individuals
Suppose that you want to randomly (and evenly) allocate 24 individuals to 3 treatments.
( alloc <- sample(24) )
## [1] 2 6 21 9 14 15 4 3 22 11 5 13 18 19 16 7 17 1 12 20 8 24 23
## [24] 10
alloc[1:8]
## [1] 2 6 21 9 14 15 4 3
alloc[9:16]
## [1] 22 11 5 13 18 19 16 7
alloc[17:24]
## [1] 17 1 12 20 8 24 23 10
