title: How to create a multi-variable "ts" object in R?
body: <p>I have have a dataframe of two different time series. I am able to create ts object separately with the following command:</p>
  
  <p>Data Frame:</p>
  
  <pre><code>    Year Grocery_Stores Liquor
  1 Feb-11         1953.8  216.8
  2 Mar-11         2108.1  240.5
  3 Apr-11         2062.3  244.4
  4 May-11         2034.8  232.1
  5 Jun-11         1988.6  223.6
  6 Jul-11         2085.9  239.0
  
  Ts_grocery &lt;- ts(dataFeed$Grocery_Stores, frequency=12, start=c(2011,2))
  Ts_Liquor &lt;- ts(dataFeed$Liquor, frequency=12, start=c(2011,2))
  </code></pre>
  
  <p>I want to bind this to and create a multi-variable time series "ts" object for my VAR model. I tried some possibilities but its not working. How I will be able to make one "ts" object? 
  Thanks in advance.</p>
