title: PCA -how are the principal components mapped?
body: <p>I have a problem with the <code>pca</code> in R, probably a simple one:  </p>
  
  <p>I have 10 Vectors a,b,c,d,e,f,g,h,i,j and bind them with <code>cbind</code>.  </p>
  
  <p>With the Result I perform a <code>pca</code>, using <code>prcomp</code>. I get the scores all right and also I get the principal components in descending order.</p>
  
  <p>Only: how on earth do I know which of the components <code>a</code> to <code>j</code> is the first, which the second and so on?</p>
  
  <p>Probably really a beginner's question - still cannot solve it and would appreciate some help.</p>
