title: Can I use function-crosslet to plot states in America?
body: <pre><code>library(rMaps)
  crosslet(
    x = "country", 
    y = c("web_index", "universal_access", "impact_empowerment", "freedom_openness"),
    data = web_index
  )
  </code></pre>
  
  <p>For this code, x="country", I want to change x to states. How can I do that?</p>
