bentonites

The data consists of 14 geological samples from the US with their major oxide
composition (SiO2, Al2O3, Fe2O3, MnO, MgO, CaO, K2O, Na2O and H2O+) and
delta Deuterium and delta-18-Oxysgen (dD,d18O).

datasets

Provides functions for multivariate analysis with compositional data. Includes a function for doing compositional canonical correlation analysis. This analysis requires two data matrices of compositions, which can be adequately transformed and used as entries in a specialized program for canonical correlation analysis, that is able to deal with singular covariance matrices. The methodology is described in Graffelman et al. (2017) <doi:10.1101/144584>. Functions for log-ratio principal component analysis with condition number computations and log-ratio discriminant analysis have been added to the package.
