title: stars() function in R
body: <p>I am struggling a bit trying to do star plots in R.</p>
  
  <p>I am currently generating the following star plot from this data frame:</p>
  
  <pre><code>   COMPACTNESS ELONGATEDNESS RADIUS_RATIO SCALED_VARIANCE
  16          96           201           32             227
  20         101           215           32             227
  33          93           154           46             162
  34         101           222           32             232
  35          87           177           40             186
  41          95           214           32             227
  53          98           228           31             236
  59         107           221           32             222
  61         103           212           34             214
  62          77           135           52             145
  </code></pre>
  
  <p><a href="https://i.stack.imgur.com/HL00I.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/HL00I.png" alt="Star Plots"></a></p>
  
  <p>The code used to generate it is:</p>
  
  <pre><code>stars(opel, main="Opel", key.labels=names(opel), scale = F,key.loc=c(4.5,12), cex=0.7, xpd=T)
  </code></pre>
  
  <p>This seems wrong to me. For example, the ratio in #16 between RADIUS_RATIO and everything else seems wrong. Also, 62 is only a straight line. </p>
  
  <p>What do I need to change in the star plot generation?</p>
