title: Parameters of rbinom() in R
body: <p>I'm new to R, and it's been a while for me and statistics. I don't understand what the parameters of rbinom are. What's is the difference between n (=&quot;number of observations&quot;) and size (=&quot;number of trials&quot;)?</p>

  <p>Thank you very much.</p>
