title: Connect xy points with spatial lines
body: <p>I have a dataset of XY points that looks like this</p>
  
  <pre><code>x&lt;-c(2,4,6,3,7,9,1)
  y&lt;-c(6,4,8,2,9,6,1)
  id&lt;-c("a","b","c","d","e","f","g")
  dataset&lt;-data.frame(cbind(x,y,id))
  </code></pre>
  
  <p>I would like to connect <em>all combinations of all points</em> with spatial lines, with lines named with combinations of the points that they're connecting</p>
  
  <p>In "attributes table" that results from the output, names for spatial lines might look like this:</p>
  
  <pre><code>a_b
  a_c
  a_d
  a_e
  a_f
  a_g
  b_a
  b_c
  b_d
  b_e
  b_f
  b_g
  c_a
  etc.
  </code></pre>
