title: simulate a random number in r for an unknown distribution
body: <p>I am trying to simulate random numbers for an unknown distribution in R. I know random number generation functions like rnorm, runif and others are used for known distributions. My input data is a revenue data of 4 years with about 500 rows. I want to generate 10 random numbers for this revenue distribution. </p>
  
  <p>Thanks</p>
