title: Daily time series with ts.. how to specify start and end
body: <p>I have a daily time series that begins on Saturday and ends on Wednesday. There is a clear weekly period to it. It is stored in a vector a in R. So, I try and convert it into a time series object - </p>
  
  <pre><code>ts(a,frequency=7)
  </code></pre>
  
  <p>This gives me - </p>
  
  <pre><code>Time Series:
  Start = c(1, 1) 
  End = c(13, 5) 
  </code></pre>
  
  <p>What do the (1,1) and (13,5) mean? And what is the best way to specify start and end in this scenario. All the examples on the internet deal with yearly data, not daily.</p>
