Sample integer values

Take a random sample from a range of integer values between 1 and n. Its purpose is similar to that of sample, but that function fails when n is very large.

sampleInt(n, size, replace=FALSE)

Arguments

n

Positive number (integer); the number of items to choose from

size

Non-negative integer; the number of items to choose

replace

Logical. Should sampling be with replacement?

Value

vector of integer numbers

Examples

  sampleInt(1e+12, 10)
#>  [1] 710622452433 312746818876 855137056206 471819306724 992102828576
#>  [6]  77863946092  24708137615 575168506243 607663982083   4365209258
  
# this may fail:
#  sample.int(1e+12, 10)
#  sample.int(1e+9, 10)
