title: How to inspect the objects loaded with data in R?
body: <p>The kohonen package has a version of the wines data file (<a href="http://search.r-project.org/library/kohonen/html/wines.html" rel="nofollow">http://search.r-project.org/library/kohonen/html/wines.html</a>) where it states </p>
  
  <blockquote>
    <p>A data frame containing 177 rows and thirteen columns; object vintages
    contains the class labels. For compatibility with older versions of
    the package, variable wine.classes is retained, too.</p>
  </blockquote>
  
  <p>I have tried <code>str, attributes, ls, head, class, unclass</code>, but none of them allowed me to reveal those objects except the wines data.frame itself.</p>
  
  <p>After loading I can see in RStudio the data (wines) and these 2 objects as Values (vintages, wine.classes).</p>
  
  <p>What is the correct way to inspect these objects through the command line?</p>
  
  <p>Regards</p>
