ggstrat_samples

Combines a grainsize–depth plot and sample label plot into a single
composite figure using the <a href="https://patchwork.data-imaginist.com/reference/patchwork-package.html">patchwork::patchwork</a> framework. The two plots are aligned
and legends are collected at the bottom.

Data processing and generating stratigraphic sections
for volcanic deposits and tephrastratigraphy. Package was developed for
studies on Alaska volcanoes ("av") where stratigraphic ("strat") figures
are needed for interpreting eruptive histories, but the methods are applicable
to any sediment stratigraphy project. Plotting styles inspired by "SedLog"
(Zervas et al. 2009) <doi:10.1016/j.cageo.2009.02.009> but with
more customizable outputs and flexible data input based on best practice
recommendations for the tephra community (Wallace et al. 2022)
<doi:10.1038/s41597-022-01515-y>.
