title: Multiply all items of vector by single item of another vector
body: <p>The question is very simple. How to multiply every element of vector A by single element of vector B.</p>
  
  <p>Here is the example:</p>
  
  <pre><code>&gt; a
  [1] 5 5 5 5 5 5 5 5
  
  &gt; b
  [1] 250  252  252
  </code></pre>
  
  <p>The final result should return one object which looks similar to:</p>
  
  <pre><code>1   1250 1250 1250 1250 1250 1250 1250 1250
  2   1260 1260 1260 1260 1260 1260 1260 1260
  3   1260 1260 1260 1260 1260 1260 1260 1260
  </code></pre>
  
  <p>I've spent some time by trying do this by function <code>for</code> but I couldn't get proper result.</p>
  
  <p>Some examples how to achieve that will be perfect answer. </p>
  
  <p>Thanks.</p>
