Generate integer random numbers from range (0:10^12)

Question

I want to generate 10000 integer random numbers between 0 and 10^12. Usually, the code would look like this:

x <- sample(0:1000000000000,10000,replace=T)
         


        

Answer 1

as.integer(runif(10000, min = 0, max = (1 + 10^12)))

FYI: as.integer performs a truncation, not a rounding.

In order to test if it works you can try by generating numbers in a smaller interval (i.e. from 0 to 6) and visualize the histogram of the result to see if the result is a uniform distribution, i.e.

test <- as.integer(runif(10000, min = 0, max = (6 + 1)))
hist(test)
