NSpec.Lib

Data-Spectra

A S4 data structure containing the plant spectra and nitorgen (N) content. Spectra is organized as a matrix and is stored as a slot,
named 'spectra'. The corresponding N content is stored in the slot 'data', which is a data.frame used for storing supporting data and
plant/vegetation traits, such as here the plant N content.

datasets

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.
