    <p>There is an introductory article located in <a href = '../doc/drfit-Rnews.pdf'>../doc/drfit-Rnews.pdf</a>,
which will be published in the R News special edition on the use
of R for chemists.</p>
    
    <h2 class="hasAnchor" id="note"><a class="anchor" href="#note"></a>Note</h2>

    <p>There is a demo for each dataset that can be accessed by
  <code>demo(dataset)</code></p>
    
    <h2 class="hasAnchor" id="see-also"><a class="anchor" href="#see-also"></a>See also</h2>

    <p>On CRAN, there is another, more statistically sophisticated package with
similar functionality called <code>drc</code>. I think the advantage of my package
is its user-friendliness.</p>
