sampleInt function

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?

Returns

vector of integer numbers

Examples

sampleInt(1e+12, 10)
  
# this may fail:
#  sample.int(1e+12, 10)
#  sample.int(1e+9, 10)
