Learn R Programming

⚠️There's a newer version (1.1.15) of this package.Take me there.

rgr (version 1.1.7)

The GSC Applied Geochemistry EDA Package

Description

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.
