density_fun

Code to specify, run, and then visualize and analyze the results of
Ixodidae (hard-bodied ticks) population and infection dynamics models. Such
models exist in the literature, but the source code to run them is not
always available. 'IxPopDyMod' provides an easy way for these models to be
written and shared.

density_fun function

<dl><dt>x</dt>
<dd>Predictor 1 in transitions table. Numeric vector indicating host
density for each of the host species. Length should be equal to the number
of host species.</dd>
<dt>y</dt>
<dd>Predictor 2 in transitions table. Number of feeding ticks in life
stages specified by predictor 2.</dd>
<dt>a</dt>
<dd>Parameter <code>a</code> in parameters table.</dd>
<dt>b</dt>
<dd>Parameter <code>b</code> in parameters table.</dd>
<dt>c</dt>
<dd>Parameter <code>c</code> in parameters table.</dd>
<dt>pref</dt>
<dd>Parameters named <code>pref</code> in parameters table. Numeric vector of
length equal to the number of host species. Values are the preference for
ticks in a given transition for each host species.</dd></dl>
