title: Details of lm function in R
body: <p>If in R I use the line:</p>
  
  <pre><code>linear &lt;- lm(y~x-1)
  </code></pre>
  
  <p>R will find a regression line passing by the origin.</p>
  
  <p>My question is, the origin is x=0 or the lowest of the x values?</p>
  
  <p>FOr example if my x values are 1998 to 2011, the fitted line will pass by 1998 or the year 0?</p>
