title: Define interval to create a continuous vector
body: <p>I can't find how to tell R that I want to make a kind of "continuous" vector.</p>
  
  <p>I want something like x&lt;-c(-1,1) to give me a vector of n values with a specific interval (e.g, 0.1 or anything I want) so I can generate a "continuous" vector such as </p>
  
  <pre><code>x
  [1]  1.0 -0.9 -0.8 -0.7....1.0
  </code></pre>
  
  <p>I know this should be basic but I can't find my way to the solution.</p>
  
  <p>Thank you</p>
