title: R code coverage for the testthat package
body: <p>Is there any tools to evaluate code coverage for R scripts using the <code>testthat</code> package? I found nothing by Google except a mention of the topic in the <em>Future work</em> section of <a href="http://journal.r-project.org/archive/2011-1/RJournal_2011-1_Wickham.pdf" rel="noreferrer">an RJournal article</a>.</p>
