Getting Started with R,nipulation, statistical analysis and graphics. R is an implementation of the S language developed at Bell Laboratories (Venables et al. .) in the 1980s. While R is an integrated environment for data manipulation, it is mostly used for statistical analyses.

Selection of the Samples for Laboratory Analysis,cal analysis. The reason is that spectra are fast and cheap to retrieve, while a single soil analysis (e.g. for soil clay) is relatively slow, and significantly more costly, to obtain. One must select a ‘representative’ subset of soil samples to be sent to the laboratory (Daszykowski et al. .).

Similarity Between Spectra and the Detection of Outliers,ctra into groups of similar characteristics or more generally for detecting outlier spectra. To assess similarity, we usually compare two spectra wavelength by wavelength and compute the distance between them. The distance between the two spectra is averaged into a single similarity metric.

Book 2021ge for performing such analyses. It is intended for students, researchers and practitioners looking to infer soil information from spectroscopic data, focusing mainly on, but not restricted to, the infrared range of the electromagnetic spectrum. Little prior knowledge of the R programming language
