title: generate random sequence and plot in R
body: <p>I would like to generate a random sequence composed of 3000 points, which follows the normal distribution. The mean is c and the standard deviation is d. But I would like these 3000 points lies in the range of [a,b].</p>
  
  <p>Can you tell me how to do it in R?</p>
  
  <p>If I would like to plot this sequence, if Y-axis uses the generated 3000 points, then how should I generate the points corresponding to X-axis.</p>
