Here is a quick, draft demo on extracting soils data from a PedonPC database, and performing some common analysis with functions from AQP. The newly released soilDB package makes it possible to rapidly extract soils data from PedonPC, local NASIS, and SDA. Thanks to Jay Skovlin for his contributions to this package and his knowledge regarding the structure of these databases. The soilDB package will arrive on CRAN by the end of the week, and a more complete demo should be ready soon. These examples can be run offline, on a non-Windows computer, or without the soilDB package-- by downloading the attached Rda file at the bottom of the page. Unfortunately the PedonPC and local NASIS connectivity only works on Windows- sorry. SDA queries should work on any platform. Windows binary packages for the dependencies can be found here.
