This is the early portions of a demo (worked examples and exercises) demonstrating use of the profileApply() function from the R package aqp.

It loads a dataset, called `loafercreek` from the R package `soilDB`.
The analysis is supported by the package `sharpshootR`. These packages are in large part developed by Dylan Beaudette, but there now are many contributors within NCSS.
