body: <p>I have one csv file in which I have 2 closing prices of stock(on daily basis)</p>
  
  <pre><code>Dates   Bajaj_close Hero_close
  3/14/2013   1854.8  1669.1

  <p>I want to convert above data into time series format. (start date is <code>3/14/2013</code>
  and end date is <code>3/13/2015</code>) I have tried this but its giving me some weird output</p>
  
  <pre><code>values &lt;- bajaj_hero[, -1]  (excluded first column i.e date in real dataset)
  bajaj_hero_timeseries &lt;- ts(values,start=c(2013,1),end=c(2015,3),frequency=365)
  </code></pre>
  
  <p>Output is:</p>
  
  <pre><code>           Bajaj_close Hero_close
  2013.000     1854.80    1669.10
