title: create continuous scale in increments of 2 or "n" numbers R
body: <p>Let's imagine I want to create a continuous scale of numbers and assign it to an object. I'd to the following:</p>
  
  <pre><code>a &lt;- 1:100
  </code></pre>
  
  <p>This will give me an array that increments every 1 number.</p>
  
  <p>Now what if I wanted to create a similar array but instead have it increment every other two numbers  so that I'm basically left with 50 values in that way:</p>
  
  <pre><code>a=    
   1 3 5 7 etc.
  </code></pre>
  
  <p>I have a feeling that that is not just an R thing of course because I have a feeling that it is basic programming stuff that I don't know... But couldn't find anything through my searches (which I think is probably due to bad keyword choice on my part).</p>
