%description
Provides easy-to-use tools for data analysis and visualization for
hyperspectral remote sensing (also known as imaging spectroscopy), with a
particular focus on vegetation hyperspectral data analysis. It consists of
a set of functions, ranging from the organization of hyperspectral data in
the proper data structure for spectral feature selection, calculation of
vegetation index, multivariate analysis, as well as to the visualization
of spectra and results of analysis in the 'ggplot2' style.
