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] 900421502768 126839369303  59632766061 818412929075 860316375504
#>  [6]  45199630550 224530511769 704817934894  98695662106  15891074902
  
# this may fail:
#  sample.int(1e+12, 10)
#  sample.int(1e+9, 10)
