title: paste quotation marks into character string, within a loop
body: <p>Using R, I want to produce multiple character strings such as:</p>
  
  <pre><code>"modelCheck("var1_d.bug")"  
  "modelCheck("var2_d.bug")"  
  ...  
  "modelCheck("var10_d.bug")"
  </code></pre>
  
  <p>I would usually use a for loop and paste (if I did not have to worry about the double quotation marks) as such:</p>
  
  <pre><code>for(i in 1:10){
      str&lt;-paste("modelCheck(var",i,"_d.bug)",sep="")
      print(str)
  }
  </code></pre>
  
  <p>However, I need to include the double quotation marks within the character string, hence the appeal for help?    </p>
