title: Converting Date and Vector in to Timeseries
body: <p>I have a separate vector of prices(r) and dates(d) the data is in order. I tried to convert prices vector in to time series specifying the start and end date and frequency .</p>
  
  <pre><code>timeprice=ts(r,start=c(2000,9),end=c(2014,8),frequency=12)
  </code></pre>
  
  <p>When I do this the series starts from 2001 and not 2000. Can anyone tell me the reason?</p>
  
  <pre><code>r
   1587.62 1586.19 1573.66 1550.37 1558.89 
   1574.17 1602.98 1633.43 1664.14 1702.75
  
  d
  9/30/2000  10/31/2000 11/30/2000 12/31/2000 1/31/2001 
  2/28/2001  3/31/2001  4/30/2001  5/31/2001  6/30/2001
