machineOperators

The data set from Aitchison (1986), p. 382, contains 
compositions of eight-hour shifts of 27 machine operators. 
The parts represent proportions of shifts in each activity: 
high-quality production, low-quality production, machine 
setting and machine repair.

datasets

The package includes methods for imputation of
        compositional data including robust methods, (robust) outlier
        detection for compositional data, (robust) principal component
        analysis for compositional data, (robust) factor analysis for
        compositional data, (robust) discriminant analysis for
        compositional data (Fisher rule) and (robust) Anderson-Darling
        normality tests for compositional data as well as popular
        log-ratio transformations (alr, clr, ilr, and their inverse
        transformations).
