gghotelling: Hotelling's T² Ellipses and Outlier Detection for 'ggplot2'

Calculate Hotelling's T² ellipses and detect multivariate outliers both for base R plots and 'ggplot2' plots. Optionally, uses robust covariance estimation to reduce the influence of outliers on the ellipses. Also included: bagplots, kernel density plots and outlier diagnostic plots.
