title: How could I output several plot and values in R function?
body: <p>There are several questions:</p>
  
  <p>1 In an R function, "return" only can output one plot or value. But now, I want the function output every plot or vector I require, how could I achieve that. Which code should I use.</p>
  
  <p>2 I have a series of variables : Game1~Game10 and I built up a do loop to analysis each of them where I represented their name as<br>
  <strong>"paste("Game",i, sep="")",</strong><br>
  But it is characters, and I cannot do it like a variable like<br>
  <strong>"sort(eval(paste("Game",i, sep="")))"</strong><br>
  is fail. How could I make R recognize the characters series as a variable name.</p>
