infoGWauxs, Auxiliary methods for infoGW and similar groundwater level data objects and other helpful utilities

The infoGWauxs package in the R language provides auxiliary methods for data merging, duplicate-record removal, and monthly rollup of groundwater levels in the so-called infoGW or GWmaster data objects. These data structures are particularly well suited for statistical analyses of groundwater levels. This package is part of a greater body of data processors oriented around the infoGW standard. The https://code.usgs.gov/map/gw/infoGW is the subgrouping organizational level of this and related software. Citations provided within infoGWauxs documentation point to additional software and interpretive studies based on the infoGW standard. Further details about the package can be found at its homepage at https://code.usgs.gov/map/gw/infoGW/infoGWauxs or after package installation.
