Geological Survey of Canada (GSC) R functions for
exploratory data analysis with applied geochemical data, with
special application to the estimation of background ranges and
identification of outliers, 'anomalies', to support both
environmental studies and mineral exploration.  Additionally,
there are functions to support analytical data QA/QC, ANOVA for
investigations of field sampling and analytical variability,
and utility tasks.  NOTE: function caplot for
concentration-area plots employs package akima, however, akima
is only licensed for not-for-profit use.  Therefore,
not-for-profit users of rgr will have to independently make
package akima available through library(akima); and use of
function caplot by for-profit users will fail.

An interface between the 'GRASS' geographical information system ('GIS') and 'R', based on starting 'R' from within the 'GRASS' 'GIS' environment, or running a free-standing 'R' session in a temporary 'GRASS' location; the package provides facilities for using all 'GRASS' commands from the 'R' command line. The original interface package for 'GRASS 5' (2000-2010) is described in Bivand (2000) <doi:10.1016/S0098-3004(00)00057-1> and Bivand (2001) <https://www.r-project.org/conferences/DSC-2001/Proceedings/Bivand.pdf>. This was succeeded by 'spgrass6' for 'GRASS 6' (2006-2016) and 'rgrass7' for 'GRASS 7' (2015-present). The 'rgrass' package modernizes the interface for 'GRASS 8' while still permitting the use of 'GRASS 7'.
