title: generate poisson distribution using R
body: <p>I need to generate poisson distribution of different lambda contained in a vector(length of 50), use the result as a new vector of lambda and then do it for 10 times repeatedly. I know I can do it with <code>for</code> but it seems lousy. Is there any good techs?<br>
  BTW: <code>rpois(50, seq(1,10))</code> seems not working. </p>
