fix.test.asis

A set of test data to demonstrate how negative values are changed to half their positive value. Optionally numeric coded values representing missing data and/or zero values may be replaced by <code>NA</code>s.
The <code>.csv</code> file was read without deleting ID, the row (observation) identifier in the first column, from the header record, and with <code>as.is</code> set to <code>as.is = c(1)</code>. Therefore the character row ID is saved as a character variable, not as a factor variable. If ID had been deleted from the header record the row ID would have been stored as dimnames(fix.test)[[1]].

 datasets

Geological Survey of Canada (GSC) 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 mineral exploration and environmental studies.  Additional functions are provided 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(....); and use of function caplot() by for-profit users will fail.
