isoStack

Combine multiple isoscapes into a single data object, including optional reconciliation of raster properties.

Routines for re-scaling isotope maps using known-origin tissue isotope data, assigning origin of unknown samples, and summarizing and assessing assignment results. Methods are adapted from Wunder (2010, in ISBN:9789048133536) and Vander Zanden, H. B. et al. (2014) <doi:10.1111/2041-210X.12229> as described in Ma, C. et al. (2020) <doi:10.1111/2041-210X.13426>.

<dl> <dt>...</dt>
<dd>Two or more SpatRaster isoscapes, each with two layers, or <code>rescale</code> objects as produced by <code>calRaster</code>. For objects other than <code>rescale</code>, the first layer in each should contain the tissue-specific isoscape and the second the isoscape prediction uncertainty (1 standard deviation).</dd> <dt>clean</dt>
