This report requires loading several related objects into your NASIS Selected Set, including Area, Legend Mapunit, Correlation, Component Pedon, Pedon and Site Observation.

A useful NASIS query that gets all of the necessary objects is NSSC Pangaea: Area/Legend/Mapunit/DMU/Pedon/Site by areasymbol.

• This query has detailed instructions for loading necessary data, and includes only representative data map units. Several other variants of this same query can be used to obtain data based on component or pedon information rather than area symbol.

Open report.Rmd, review the "params" section of the YAML header to select target mapunit and cache file name, then click "knit". You can cache the data for many map units (e.g. a whole soil survey area) once, then re-run the report several times with different musym values. To force new data to be loaded from the database, delete the .rda file specified in cache_file in the document directory.
