slice

The function will slices time with a given set of boundaries and produce a time scale object if desired.

Functions to describe sampling and diversity dynamics of fossil occurrence datasets (e.g. from the Paleobiology Database). The package includes methods to calculate range- and occurrence-based metrics of taxonomic richness, extinction and origination rates, along with traditional sampling measures. A powerful subsampling tool is also included that implements frequently used sampling standardization methods in a multiple bin-framework. The plotting of time series and the occurrence data can be simplified by the functions incorporated in the package, as well as other calculations, such as environmental affinities and extinction selectivity testing. Details can be found in: Kocsis, A.T.; Reddin, C.J.; Alroy, J. and Kiessling, W. (2019) <doi:10.1101/423780>.

slice function

<dl><dt>x</dt>
<dd>(<code>numeric</code>) Vector of continouos age/time estimates.</dd>
<dt>breaks</dt>
<dd>(<code>numeric</code>) Vector of boundaries, the breaks argument of the <code><a href="/link/cut?package=divDyn&version=0.8.3" data-mini-rdoc="divDyn::cut">cut</a></code> function</dd>
<dt>offset</dt>
<dd>(<code>numeric</code>) Single value. If desired the resulting integer bin numbers can be offset by some amount.</dd>
<dt>ts</dt>
<dd>(<code>logical</code>) Should a time scale object be also produced when the function is run?</dd>
<dt>revtime</dt>
<dd>(<code>logical</code>) Should the time dimension be reversed? This argument is set to <code>TRUE</code> by default, meaning that the function will reverse the order of time: smaller values of <code>x</code> will be translated to higher values (<code>slc</code>) in the function output.</dd></dl>
