&lt;p&gt;&amp;lt;sup&amp;gt;Created on 2019-03-14 by the [reprex package]( (v0.2.1)&amp;lt;/sup&amp;gt;&lt;/p&gt;
Full set of changes
&lt;li&gt;Any interval &lt;code&gt;seq.Date()&lt;/code&gt; can handle (e.g. "5 weeks") can be handled by
&lt;code&gt;incidence()&lt;/code&gt; (see &lt;a href=""&gt;;/a&gt;)&lt;/li&gt;
&lt;li&gt;Weekly intervals can start on any day of the week by allowing things like 
"epiweek", "isoweek", "wednesday week", "2 Saturday weeks", etc.
(see &lt;a href=""&gt;;/a&gt;)&lt;/li&gt;
&lt;li&gt;the item &lt;code&gt;$weeks&lt;/code&gt; is now added to the incidence object, which contains an
"aweek" class&lt;/li&gt;
&lt;li&gt;plotting will now force the first tick to be the starting point of the
incidence curve&lt;/li&gt;
&lt;li&gt;&lt;code&gt;make_breaks()&lt;/code&gt; will automatically calculate breaks from an incidence object
for plotting. &lt;/li&gt;
&lt;li&gt;&lt;code&gt;scale_x_incidence()&lt;/code&gt; will produce a ggplot2 "ScaleContinuous" object to add
to a ggplot.&lt;/li&gt;
&lt;li&gt;&lt;code&gt;plot.incidence()&lt;/code&gt; argument &lt;code&gt;labels_iso&lt;/code&gt; is deprecated in favor of 
&lt;li&gt;Incidence objects will still have &lt;code&gt;$isoweeks&lt;/code&gt; if the weeks are ISO 8601
standard, but users should rely intead on &lt;code&gt;$weeks&lt;/code&gt; instead. The &lt;code&gt;$isoweeks&lt;/code&gt;
element will be removed in a future version of incidence.&lt;/li&gt;
&lt;li&gt;&lt;code&gt;as.incidence()&lt;/code&gt; argument &lt;code&gt;isoweeks&lt;/code&gt; has been deprecated in favour of 
&lt;li&gt;ISOweek import changed to &lt;a href=""&gt;aweek&lt;/a&gt;&lt;/li&gt;
&lt;li&gt;Vignettes have been updated with examples.&lt;/li&gt;
