<p>The R package <strong>pfm</strong> provides some utilities for fate modelling, including dealing with FOCUS pesticide fate modelling tools, (currently only TOXSWA cwa and out files), made available under the GNU public license.</p>

<h2 id="installation">Installation<a class="anchor" aria-label="anchor" href="#installation"></a>
</h2>
<p>The easiest way to install the package is probably to use the <a href="https://jranke.r-universe.dev/pfm" class="external-link">r-universe repo</a>:</p>
<div class="sourceCode" id="cb1"><pre class="downlit sourceCode r">
<code class="sourceCode R"><span><span class="fu"><a href="https://rdrr.io/r/utils/install.packages.html" class="external-link">install.packages</a></span><span class="op">(</span><span class="st">"pfm"</span>, repos <span class="op">=</span> <span class="fu"><a href="https://rdrr.io/r/base/c.html" class="external-link">c</a></span><span class="op">(</span><span class="st">"https://jranke.r-universe.dev"</span>, <span class="st">"https://cran.r-project.org"</span><span class="op">)</span><span class="op">)</span></span></code></pre></div>
<p>Alternatively you can install the package using the <code>remotes</code> package. Using <code>quick = TRUE</code> skips docs, multiple-architecture builds, demos, and vignettes.</p>

<p>One recent nice example of the usage of this package is the visualisation of a time weighted average for a sawtooth curve obtained from several overlays of mkinfit predictions as shown <a href="http://pkgdown.jrwb.de/pfm/reference/plot.one_box.html" class="external-link">here</a>.</p>

<p>Calculations of predicted environmental concentrations using this package have been used in some publications by Agroscope.</p>
