title: Concat String with variable value to form New Variable
body: <p>I have to make dynamic variable which store different value as given in pseudo code</p>
  
  <pre><code>for(i in 1:30)
   "Day"+i &lt;- sqldf("select * from call_details where day ="+i)
  </code></pre>
  
  <p>Is it possible in R or not and if possible then how? I just able to concat the string (using <a href="http://stat.ethz.ch/R-manual/R-patched/library/base/html/paste.html" rel="nofollow">paste</a>) which store the concated string as character but couldn't able to store value on it. Also I could not able to find out how to pass variable on sql query statement.</p>
